Will not print the error light and the drum light flash. Replaced drum but still will not print and error light and the drum lights still flash.

Fuser error

We have just changed our drum unit but the drum light is still flashing. The printer is printing though. Any suggestions?

When all lights flash it's a service problem. You press and hold the go button and see what lights are on then.error light means main PCB failure, Toner light means fuser failure, drum light means laser failure. Toner and error light means main motor error, drum plus error light means its a fan failure.

After replacing fysicalythe photoconductor/imagaging drum, leave the door open. Press and hold Cancel untl all lights flash in sequence to reset the printer. Close front cover.

The error that you are giving me, is that the drum needs to be replaced. Replace the drum, and follow instructions in the package to reset the counter.

thank you

Leave the printer on. Open the front and hold down the cancel button until all the lights are flashing in sequence. Close the front while still holding the cancel with the lights flashing and then release the cancel button. This should reset it.

Thanks

Have you replaced the printer drums? The status monitor will tell you what percent they are at (similar to the toner cartridge status). This fixed my problem before.

hold cancel button down with door open, this should rest it

Hi, to reset drum light follow this sequence: press cancel, exposure, cancel, exposure. Display goes blank, enter 24, print, 07 print, cancel cancel. Cheers
