Hello,

You may have a high voltage power supply problem. Here is the info from the service manual about that error.

Check the voltage at J15-3. The voltage changes from +24 V dc with the printer idle to 0 V dc when the printer runs the print test. If the voltage is incorrect, check the continuity of line J15-3 in the front cable harness to the HVPS. If there is no continuity, replace the cable harness. If there is continuity, replace the HVPS. If the problem continues, replace the system board.

Your error message diag/repair is a bit involved. If you need a service manual we have them in available for $6.95 in electronic form. W also have repair parts in stock for this unit, email me if you need parts prices.

I hope this helps you, if so please rate my solution.

Printer displays 917.00 print error. seems to be transfer roller. changed the transfer roller same error.


The exact definition of this error is "Problem with transfer-transfer servo start error"... NOT the transfer roller. The service manual directs you to the Transfer roll service check.

The service check tests for proper operation of the HVSP, system board, and sensors.

The most likely cause of your problem is the HVSP ( High Voltage Power Supply ).

Change the HVPS and you should be good to go!

Error code 917.00 "service transfer roller" won't clear


This is a transfer roll error. Take the toner cartridge out and clean the area under it. The transfer roll is a roller which is right under the toner cartridge. make sure the ie is clean . It may need to be replaced.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Lexmark t640 error message


"Remanufactured cartridges" How do you define that?

Given that Lexmark does not support or condone the use of third party products in their printers.

When a cartridge is new from the factory, all of the components inside the cartridge are new.

When Lexmark sell a recycled cartridge, all of the components within the cartridge are ETN components (Equivalent to new).

That means all of the rollers have been change and the PC is new.

It seems you purchased a cartridge which has a defect.

Return it to your point of sale and see what happens with the next one.

Lexmark t644 error code 917.00


This error indicates that there is a charging problem with the transfer roller. You could start by cleaning the contacts for the transfer roller (power off printer first). The transfer roller is the black foam-like roller under the toner cartridge. Handle it with paper because the oils on your hand could damage it. To remove it, just pry under the far left side with a screwdriver. Lift and pull to the left to remove. If this does not fix it, then you have a more serious problem. It could be one of the arms or the HVPS.
