Lexmark C510 Code error: 995 Service Engine Error

SOURCE: 900 service error with lexmark printer

OK, a couple of things... Some earlier Lexmark units had code on both a RIP board (raster image
processor) and an engine board. In this case, the code would have to be reloaded into both
boards. Fortunately, this can be done even if the printer will not boot to a ready state. However, if
this has already been done sucessfuly, the problem may well not be the printer but rather something
in the data stream. To confirm this, remove any and all data cables and reboot the printer. If it comes ready and you can print all the internal pages including the network config pages, then it is likely the
problem is the data stream. One must be careful when the printer is controlled by a print server
because the end user may not have control over the print que. If a corrupt or printer incomprehensible
job is stuck in the que, the printer will go to a 900 condition as soon as the network interface
initializes. This will continue until the print que is cleared.

Hope this helps...

Sean.

*************************************************

994 Service Engine Error on a Lexmark C510 ID: ENUS21233 If your printer is unable to move the photodeveloper belt to the correct position during printing, a 994 error will occur. However, it may simply be the case that the photodeveloper is either contaminated with excess toner or improperly installed. To test for and resolve this issue, please do the following:

1. Power the printer off and remove the photodeveloper cartridge.
   
2. Rotate the green metallic photodeveloper belt by manually turning the white drive gear on the bottom of the cartridge until the black positioning markers are visible.
   
3. If necessary, carefully wipe any excess toner powder from the positioning markers using a soft, lint-free cloth or tissue.
   
4. While the top cover of the printer is still open, inspect the sensor that is used to locate the positioning markers on the belt. CAUTION! The photodeveloper is very sensitive to light. Cover the green metallic surface of the photodeveloper with a piece of paper while it is outside the printer.
   
   • Refer to this image, this image, and this image to identify the location of the sensor.
   • Verify that the sensor has not come loose from its housing and that it is not contaminated with excess toner powder. If necessary, clean the sensor with a soft, lint-free cloth or tissue.
     
5. Re-install the photodeveloper cartridge and power the printer back on.
   
6. If the error remains, it is likely that a service call will be necessary to resolve this issue. Please contact Lexmark Technical Support, having first obtained the serial number of your printer. NOTE: If practicable, attempt to order another photodeveloper and replace it first to avoid the inconvenience of a potentially unnecessary service call.
