C35 style Machines... Another Peek Ahead.

Introduction to a new style: Overview & Status Codes.
Author: Britt Horvat
First published in ENX Magazine (

    This month, we'll hit on a machine with a similar name although it is a thoroughly different piece of equipment. The C35 style of machines are black and white printer / copier / fax machines. I first saw them in Staples stores for customer use. These will be approachable… you'll be able to read Status Codes and work the diagnostics without any special computers or tools. In this article, we'll look into the basics of the machine including the Status Code meanings. We'll also look at how to get into the diagnostic mode. Next month we'll delve further into the diagnostic functions, tests and adjustments.

    The C35 style models include CopyCentre C35 / C45 / & C55, Workcentre Pro35 / Pro45 / Pro55 and Document Centre (DC) 535 / 545 / 555. These are appropriately 35 copies per minute, 45cpm & 55cpm as you might expect. There were some little fax machine models (the Pro535 / Pro545) which are completely alien to this series, so watch not to get them confused. You'll also want to be aware that another group of machines: C65, C75, C90 are actually in the DC265 style and also have little if anything to do with the C35 style.

    These machines have a "Xerographic Module" which is basically the Drum Cartridge. It's a customer replaceable unit (cru) as is the Fuser Module. Both of these modules have Connectors or CRUMs on board (Customer Replaceable Unit Monitors… basically a terminator chip). So far a means of repairing / resetting these connectors has not been made available in the market, but its likely that as the demand for a way to repair these units increases, someone will figure out a way. The fuser is not broken down in the parts list beyond the entire module so you'll need to look to aftermarket sources, recoating facilities etc. to help make it possible for you to do repairs on the fusers. The fuser module is set up to time out at 350k prints. The Xerographic Module is set to run 200k prints.

    The toner is sold under the reorder number 6R1046 (or 006R01046) for a two-pack. The toner has a stated yield of 28-30k prints (assuming 6% coverage). There's a developer unit which is supposed to run a million copies before it reaches its life expectancy. These machines are dual-component (they do actually use developer material), although I did not see any sign of a part number for replacement developer. Even a thorough search of the Service Manual didn't shed much light on the developer material or why it lasts as long as it is supposed to… my guess is that it uses a trickle system where a small amount of fresh developer is mixed into each toner cartridge to continuously replenish the developer with fresh stuff. Just an educated guess.

    The Status Codes are actually pretty consistent with many of the other machines in the Xerox line; including the 5340 style and the newer DC265 style etc. The codes are 2 digits followed by 3 digits (for example 10-310). Following is a rundown of the basic meaning behind each of the prefixes (the first 2 digits) … and more specific information about the codes I suspect will become important. It's an abbreviated list (the full list including all codes would be a little unwieldy for a magazine article).

    As is common in machines these days, the Status Code is often not displayed at first… customers will likely call with vague messages which show up on the screen… you will need to instruct your customer to press the "Machine Status" button on the Control Console, then have them press the "Fault" tab on the touchscreen followed by "Active Messages"… then have them read the Status Code and the corresponding status message to you. You can also read the Last 20 Faults by pressing "Machine Status" button followed by the "Fault" tab and then press "Error Log".

STATUS CODES (see above about how to read the Status Code)
01-300: Front Door Opened during a copy run.
01-305: Left Door is open.
02-xxx Codes: UI (User Interface… Control Console) problems.
03-xxx Codes: These relate to Communication Errors between the boards… they are too numerous to list here. It may be worth trying to power down the machine, unplug it from the wall and check for any loose or damaged connectors.
    03-371: Fuser CRUM Connector Communication Failure.
   03-372: Xerographic Module CRUM Communication Failure.
   03-374: Power Off failure.
05-xxx Codes: Have to do with the DADH (Duplexing Automatic Document Handler)
    05-300: DADH opened during a copy run.
    05-305: DADH top cover is open.
06-020: ROS (Raster Output Scanner or Laser Unit) Motor Failure.
06-340 / 350: ROS Laser failure.
07-301: Tray 1 opened during a copy run.
07-302: Tray 2 opened during a copy run.
07-303: Tray 3 opened during a copy run.
07-304: Tray 4 opened during a copy run.
07-355: Tray 3 Elevator Lift problem.
07-360: Tray 4 Elevator Lift problem.
08-xxx Codes: Misfeeds & Paper Jams.
09-xxx Codes: These codes vary widely, so here's a complete list of what they mean:
    09-060: High Voltage problem… can be caused by an arcing transfer corona or charge grid.
    09-310: The Toner Dispense Motor continued to run after the low toner sensor detected that the toner dispense module is full.
   09-390: Low Toner sensed.
   09-350: Erase Lamp problem.
   09-360 / 361 / 362 / 363: Toner Concentration Sensor problems…
   09-365: Relative Humidity Sensor problem.
   09-370: Developer Temperature Sensor failure.
   09-375: Ambient Temperature Sensor failure.
   09-380: Waste toner door opened during a copy run or the waste bottle is detected as being missing.
   09-399: Incompatible Xerographic Module (wrong Connector CRUM detected on the Drum Cartridge).
10-101 thru 126: Fuser and Exit Jams.
10-315 / 320 / 321 / 323 / 340 / 350 / 360 / 380: Fuser Over Temperature problems.
10-322 / 324 / 325 / 330 / 370: Fuser Under Temperature…
10-399: Wrong Fuser CRUM connector detected (wrong market (Europe vs. US vs. Developing Markets))
11-xxx Codes: Finisher problems.
12-301: OCT (Offset Catch Tray) failure.
14-xxx Codes: Scanner and image reading problems.
   14-110: Scan Carriage Home Sensor problems.
19-xxx Codes: Video failures & out of memory failures.
20-xxx Codes: Fax problems.
22-xxx Codes: Failures during installation of new optional equipment on the machine.

    Next we'll need to learn a bit about the machine's diagnostics and customer menus so you can go in with some degree of confidence.

    The machine's customer Tools menu is found by pressing "Access" on the control console… the machine will prompt you for an access code (the default code is '1111'). This will be useful for reading the machine's copy and print count meters and also for finding out which version of the Xerographic Module and Fuser Module the machine is set up to accept. Some machines are set up for Field Service Maintenance Agreements (FSMA or "Metered" plan) and then others which are placed without a maintenance agreement will be set up for the "Sold" plan… a machine under the Sold plan will reject the Metered supplies because the machine will read the CRUM and know it's the wrong module.

    Next month we'll take a long look at the tests and adjustments available from the Diagnostic Mode. For the time being however, it is worthwhile to at least let you in on how to enter Diagnostic Mode. It may actually serve you to some degree, even without all the details, because it's menu driven and fairly easy to find your way around once you're in.

ENTERING DIAGNOSTIC MODE: To get into Diagnostics, from the powered on state you'll hold down the '#' button while then pressing the 'Access' button… You'll be asked for a password which you will then enter using the keypad (default is '1934') followed by 'enter'. If you get the password wrong 3 times in a row, there will be a 3 minute lock out period after which you can try again. Once you are in, a menu will appear which includes all kinds of goodies as follows:
Main Menu:
Service Info: For reading software versions, billing counters, serial number, prints since last call, and the Network IP address.
Fault History: Last 40 faults & fault counters.
dC Routines: Most of the diagnostic stuff is in dC Routines including NVM (memory) adjustments and component control codes. You'll need to know which code to enter for any particular test or adjustment… (will cover that next month).

   Hope this will suffice to familiarize you somewhat with this series… with this article and next months in hand, you should be able to approach these without fear. Happy repairs!


Introduction to a new style: Diagnostic Tests & Adjustments.
Author: Britt Horvat of The Parts Drop
First published in ENX Magazine (

   This is the second part of a series on a relatively new bunch of Xerox brand copier / printers which include a range of models. The C35, C45, C55 , also Workcentre Pro35, Pro45, Pro55. The DC535, DC545, & DC555 are all extremely close to one another. Last month we did an overview of the machine and its supplies… we also went over the Status Codes. Now you'll need to get some details to flesh out how to use the Diagnostic mode to test components and make memory adjustments.

   Let's start by recapping how to get into the Diagnostic Mode: To get into Diagnostics, from the powered on state you'll hold down the '#' button while then pressing the 'Access' button… You'll be asked for a password which you'll enter using the keypad (default is '1934') followed by 'enter'. If you get the password wrong 3 times in a row, there will be a 3 minute lock out period after which you can try again. Once you're in, the Main Menu will show up:
Main Menu:
Service Info: For reading software versions, billing counters, serial number, prints since last call, and the Network IP address.
Fault History: Last 40 faults & fault counters.
dC Routines: Most of the diagnostic functions are found in the dC Routines including NVM (memory) adjustments and component control codes. You'll need to know which code to enter for any particular test or adjustment… so let's get into it.

    To get into the Memory Adjustments (Non Volatile Memory or NVM), you'll select "dC Routines" and then touch "Copier Routines" followed by "131 NVM Read / Write".
    The codes are arranged like many of the Xerox models… they have 2 digits called the "Chain" followed by 3 digits which are referred to as the "Function" (for example 01-001). You can get to a code either by entering it in the code entry box which appears on your left, or you press the "Find" button and then scroll through the list of available codes. When you see the code you want to read or change at the top of the screen, press the code's description to highlight it. To read the current value in that code, touch the "Read/Write" button.
    The list of codes is extensive… there is a lot of stuff you probably won't ever play around with. Following is a list of the ones from the copier options (chains 01 through 10) which are likely to be important to most of us…We don't have the space to get into the fax related codes (chain 12 through 28) but you can get into those chains and scroll through the choices if you ever need to find something in there.

19-001 Megs of Memory (read only) 16
* Powering the machine off and back on… to clear some of the faults. Don't simply unplug the machine, it can cause memory corruption and headaches of all sorts. To power off, touch the "on/off" button… this will bring up a "power down options" window. Touch "Power Off" then "Confirm"… you'll need to then wait about one minute for the machine to shut down entirely. The Service Manual says to avoid cutting power to the machine before the power down sequence completes itself if at all possible.

** Registration Adjustments are all best approached using a special procedure explained below called "dC 604 Registration Setup"… this process sets up all of the various registration adjustments in a systematic way.

   The next thing you'll want to know about will be how to run component tests from Diagnostics. These tests are run from "DC330". You'll find both Input Codes and Output Codes all together in here. Input codes are for testing sensors, switches, etc and the output codes allow you to run motors and solenoids, clutches and so forth. You can choose up to 6 components together (as long as the components you choose are allowable together). One nice thing is that you can find component codes from the touchscreen as they are available in a scrollable menu. Here's how this works:
   Go into Diagnostic Mode and select "DC Routines"… choose between "Copier Routines" followed by "330 Component Control". You can either press the "Find" button and scroll through the entire list of codes or you can enter a "Chain Number" and scroll through only the functions in that "chain" (again, the chain is the first 2 digits of any code (ranges from 01 to 14 for copier related codes and 20 is for fax related codes). When you see a code you wish to have ready to go, touch that Components Name button and then touch "Select"… this will add the code to your short list of up to 6 readied codes (The word "yes" will appear next to that code's description. Touch "Save" to save your list which will then bring up the "Component Control Window" which is the short list of up to 6 components which you have selected. Touch a control code to highlight it and then touch "Start" to start that component's test. If it's an input code, you'll see the state of the code will show up to the right side of the component code's description (it'll say "High" or "Low" for most of the codes)

    Below is a listing of many of the useful codes available to you… I have chosen to leave off chain "20" which is the fax related stuff because it is quite lengthy… It's fortunate that you can go into chain '20' and scroll through all of the options.

    There are a couple of Adjustment related items which aren't as simple as the regular codes listed in the Memory Adjustments mentioned earlier.  First is the Developer Calibration (needed whenever new developer is installed) and second is the Registration Setup.

Developer Calibration (dC905) (Toner Concentration Sensor Calibration):
   For the Developer Calibration, you'll go into Diagnostics and select "copier DC Routines, dC 905 TC (Toner Concentration) Sensor Calibration".  Touch the 'Start' button to begin.   The message will remind you to only run the routine if new developer has been installed…  and to make sure that the developer is cammed in before starting.  The routine will energize all the needed components simultaneously in order to tone up and calibrate the sensor for the new developer.  Let it go through its entire setup…  if any of the Toner Sensor Failure codes come up: 09-360, 09-361, 09-362, or 09-363, you'll need to figure out why the machine is having trouble setting up the Toner Concentration Sensor (make sure toner dispensing is working properly).

Registration Setup (dC604):
    For the Registration, the Service Manual has you use a routine called "dC 604 Registration Setup". Start with "Image Output Terminal Registration, Side 1 / All Trays / Print Test Samples"…  this is to say, you'll want to set up the general registration for the paper path first before playing around with the scanner registration, the document feeder registration, or an individual tray's registration.  As you follow the prompts, the machine will spit out 3 Registration Test Prints with a scale with numbers near each of the edges of the sheet.  Each edge is named… "Zone A" through "Zone D".   You'll be prompted to adjust Zone A …  enter the number of the scale which is at the edge of the sheet.   Now, you'll select "Scanner Registration" and follow the touchscreen prompts.  Take one of the Test Prints and place it on the platen glass.  The rest is similar…  Next comes the "Document Handler (DADH) Registration" which is handled the same way.   Finally, you can select individual trays if necessary.  

Running Test Prints from Diagnostics:   Another goodie is the ability to run Test Pattern Prints from diagnostics.   This is extremely useful in troubleshooting copy quality problems.  When you run a Test Pattern from the machine's logic, you eliminate the optics / reading part of the machine from the equation.   The Test Patterns are in DC Routines under dC606 Print Test Patterns.   You'll go into diagnostics and choose "Other Routines", select Image Quality Test Patterns 1-19, select your desired features, 1 or 2 sided print and the paper size to use for the pattern.   You then also choose if you want a label or a border on the sheet.   Then select "Save" followed by "Start Test" button.

    That should do it!   I'm sure there will be other things which will come up over time, so once we all get our feet wet and I start getting some good feedback from the field, we'll revisit this series.   We'll also probably need to have a good look at the Drum Cartridge and the Fuser. Its still rather early for these as they are still under OEM care in most cases, but they are quite popular and bound to be showing up at a customer near you sometime soon.   See ya next month!
