Re: ir7095 print blur

You're going to need to isolate the area of the problem. Open the door and trick the switch do some prints and deliberately jam the machine. Take note of the paper locations and see where the printing gets blurry first. Also look at the drum at the part that still has toner on it before it would have been transferred to the paper. If the image on the drum if fine then the pre-charge unit, laser, drum, and developing unit/mag roller are all fine.

Look at the toner on the paper after the drum but before the fuser. How does it look? Get the idea? Tell us where the blur starts. Is it just printing or copying too? Print a blank page, is there dark residue, if so you have a drum blade problem.

post a picture----
is it on prints and glass copy--

Check to see if the Lower Transfer Guide is too low. There are two adjusting posts that are slotted. These posts adjust the height of the Lower Transfer Guide. Check to see if the posts are at the mid-point. They may be all the way to the left (lowest setting). If they are, loosen the locking screw and move to the mid-point position. Take care when tightening the rear screw, over tightening will cause guide to move to the lowest position. If you move the post to far to the right, the blur may shift to the lead edge.

Re: ir7095 print blur

This seems like toner issue. You gonna make sure you are using GENUINE toner. And i will do cleaning at all.
Cleaned scanner lamp and scanner mirrors using spirit.
Rebuild developer, throw all the toner out and clean the developer cylinder using appropriate liquid
and you may try to clean the laser unit too

Re: ir7095 print blur

all i already done.toner is original.

pls refer to image

not a BLUR Issue------------------

TONER or Transfer issue

check the coating of Toner on the Developer Mag roller --
If the Mag Roller coating is uneven, inspect the two gears on the rear of the Developer Assembly.

What happens If you turn potential control off ?????

Perform a panic stop and checking the image on the drum see if it is light--------------
If Light--------------check & clean The Laser Dust Proof Glass

Also-Check visually to make sure that blanking lamps are coming on.
You should see a red glow next to primary corona, and don't forget to cheat the laser shutter when looking or else it will generate an E110 .
The DC controller sends 24v dc to turn on lamps. You should also not read any continuity when ohming lamps at connector.
If you do read continuity most likely the short also took out DC controller and you will have to replace them both at the same time.

AGREE with tekcat. Toner or xfer issue. Inspect dv unit cylinder. If none of the above the laser unit might be the problem.
