IR 2270 Heart Beat

[Gerhard]

Hi Guys

I need some input please. I have a IR2270 with about 600 000 on the clock giving me a weird copy quality problem. I have attached a copy of the problem. The problem varies all over the page, but only one time per page and only one in five pages are effected. I have replaced drum unit/ dev unit/ laser unit/ the whole right hand door.

Please advise

Regards

Gerhard

I had that once on an IR3300 & where the line lifts up it went rite up & off the page it turned out to be drum unit, if you have fitted a complete genuine unit then it coultd be arcing drum earth or bias contact to the dev unit. Whatever it is i would say its arcing & generating elecrical noise. Good luck hope you get it sorted.

That is a Grounding Issue> see below>>>>>

A 'wavy' image is occurring from both copies and prints.

Check if the grounding spring on the steel registration roller is making proper contact. Reforming the ground spring on the left hand side of the registration roller; so that it properly touched the metal registration roller resolved the image fault.

**Check if the ground leaf spring for the registration roller is deformed. Reform or Replace the Leaf Spring to resolve. ( Part number for the leaf spring is FC5-1564-000 )

Could be the drum.

Check your transfer roller as well.

Also check the positioning pin that's circle in orange.

They sometimes break causing image and jamming issues

Looks like you've replaced all the major assemblies.
Try reseating all the connectors and memory on the main controller and DC controller. Cut any wire ties going to the laser. Check the routing of all the wires coming off the main controller, make sure they aren't pinched by the cover or going out the wrong cutouts. I've seen similar distortion like that on other models and it usually has something to do with the memory or laser. Most of the time it seems to go away after checking all the connectors. GL

Make test prints (not copies) ,is it good ?
Then it is the reader unit stumbling on something maybe.

I believe that's a page from a P-print, done from service mode, so its an internal issue.

I still get your point though.

And he never really stated how the copy was made.

Off a 900k 2270 -

Was a dirty grounding leaf spring as already said.
Very easy to take off and clean. 2secs to check.

I had this same issue, mine was resolved by replacing the entire front portion of the registration/transfer assembly. It included the transfer and registration rollers in the unit. After that, no more problems. Before that, I had tried all manner of parts to no avail. I always assumed it was some type of voltage spike causing the timing to the laser to get screwed up.
