Prints very light even when the dargest setting is selected


Please replace toner carridge. Then print demo page through report menu.
If problem persist then the photoconductor have to be replaced. Most likely 95% of cases are bad or defective toner cartridge or photoconductor, if change toner doesn't fix the problem then you would like to get a technician to pin-point the problem instead of start replacing parts. Good Luck!

When printing in book fold on my new acer laptop each half of the page is printing on a separate sheet although i have printed in this form once before.


this problem was not resolved as my problem did not relate to a gestetner machine but a Lexmark printer. At no time did I declare what machine I was using, and can only assume that the mix up occured when I was re connected after my first connection had ended prematurely.

Black streaks on copies


Sounds like the drum unit has some scarring on the surface and it is causing toner to be picked up in the grooves and placed on to every single page that is printed on the printer.

Pull the drum unit out of the copier and inspect the surface, being careful not to touch it as the oils of your skin will damage the drum surface. If you have scarring around the green/blue/black drum surface then you need to prder a new drum unit.

Hope this helps,

Cheers,

Keith

The sensor for this error is in the black imaging unit not the toner hopper. See the steps below. If that doesn't work then visit my website1.gif for contact and I will sell you a full service and or parts manual on CD.
