093-311 – Toner Dispense Failure

First you’ll want to figure out what caused the toner dispense failure. 

• Check the Dispenser Auger and gears for binding or damage.  Clear out any clumped up (impacted) toner. 
• If the toner was not bound up anywhere, then you’d want to check and test the Toner Dispense Motor.  To test the motor, you can first measure resistance across pins 1 and 2 on the motor’s connector.  A measurement between 22 and 27 ohm would be normal.  You can also run the motor from Component Control (IO check) in diagnostics using code 093-003 (the motor will run for 2 seconds when you hit start).  (note it might be necessary to first clear the fault code from NVM Read / Write to get the component control to work… read below about resetting the fault code).
• Check for bent, broken, or dirty pins (oxidation buildup)… try disconnecting and re-connecting the connectors a few times to help clean the oxidation off of the pins.  This only serves as a temporary fix if it works… you will want to come back to each connection and apply Stabilant 22a when you have the problems solved and you’re ready to reconnect it all for the final time.
• Also check the Low Toner Sensor to make sure there is no impacted toner against the round face of the sensor.  If so, clean the sensor’s face or replace the sensor if necessary (130E82720)

Once you solve the mechanical problem or replace any bad parts, you will need to reset the Fault Code.  This will require three things to happen:

• First you will need to go into Diagnostics and reset NVM Read / Write code 762-084 back to “0”.
• Second you should make sure the toner cartridge is actually a good one.  Make sure it still has a good amount of toner in it.  Also note that it’s possible for the cartridge to have fused or clumped toner inside of it (for example a toner cartridge which was stored in high heat such as the back of a technician’s car).  If you put something over the hole in the end of the cartridge, you can shake the cartridge and listen carefully… you should not hear anything rattling around inside there…
• Third… If you determine that the toner cartridge is ok… and it still has toner in it, you will still need to order a new Toner CRUM chip: D95TRC (or D136TRC for D136 models only).  The new CRUM chip will be necessary to get the machine to accept that toner cartridge again.  If you don’t replace the CRUM chip, the machine will continue to instruct you to replace the Toner Cartridge.  If you have another new toner cartridge handy, you can install that until you get the replacement Toner CRUM chip.  Make sure that the customer knows to shake the new cartridges a bunch of times before installing them… this will assure there is no clumped up toner inside there from storage.  To help with that, it’s wise not to store this type of toner cartridge on their ends
