This comes from the manual for your device:
A blank sheet is ejected.
You placed the document facing the wrong way when using the copier.
The other party placed the document in their fax machine the wrong way. Check with the other party (KX-MB781 only).

Try putting a page in and seeing if it copies blank and then putting it in the other direction. Have you had the same issue with printing?

If everything comes out blank it is the fuser or heating element.

Was the copier working fine before you changed the cartridge? If so I think your cartridge is the problem. If it started making blank copies right after you changed it. If this is not the case the first thing I would say is it is not the drum. Try opening and closing the right side door. There are contacts in the door that will cause blank copies. I have had several customers do this and it fixed the problem. You can also try pulling out the toner and then pull the drum unit partially out and re-seat it. Then re-install the toner.
Good Luck

Copy coming out blank


Normally a blank copy is caused by the image not being transfered from the drum to the copy paper. Which indicates a problem with the transfer step of the process, check for a bad transfer roller or a bad transfer belt. If this is not very obvious, run a copy and try to turn the machine off or open the front cover during the copy process when the copy paper is about half way under the drum and check for a toner image on the drum. If there is no toner image on the drum you may have a developer problem, broken drive gears etc. But if there is a toner image on the drum but no image on the paper then it is a transfer issue.

Had toner life end message. Replaced toner and drum with oem,machine reset but now just making blank copies. Tried to print internal report that's blank too


To reset the sensor after installing a new toner cartridge follow these steps.
1. With unit powered On, open the front cover.
2. Press the "Options" key. Display will show "Replace Drum?"
3. Press "Start" key.
4. Press 1,0 .
5. Display will show "Accepted" for approximately 2 seconds. Then display will change to "Cover Open".
6. Close cover and see if Toner Life End error message has gone.
Please note that this must be done with a new cartridge so the unit will see that there is toner in the cartridge.

Sharp al1631 copier, copys are too Dim settings don't help ?


Check the toner supply, it may be running out of toner. Check the bottle or cartridge for correct install. Turn the machine on and let it warm up, Recheck the copy quality. If it is still light run a dozen blank copies, then a test copy if it is improving the toner is depleted and need to catch up, if it isn't there may be a problem with the toner add system.


Hope this is of some help.

Blank Streak down left side of copy


One way to tell is to take out the toner cart and shake it, reinstall and test run. If it comes out better you may be running out of toner in the cart and will need to replace it shortly. The drum and toner cart on this machine are in the same unit.
Hope that helps...

Leaves about a 1/4 inch space down middle of paper.


That is the cleaning assembly in the drum cartridge.Either something slipped into the cartridge or the blade tucked. Sounds more like something is in the cartridge blocking the drum from both cleaning and charging/

Blank lines on paper


Maybe

 

Toner cartridge low?

Shake gently and do another test is image improved?

 

If so replace Toner.

 

Failing this does lines disappear when using old drum again?
