You didn't mention make or model so I will guess. Most of the Savin/Ricoh brand small machines that have a small pcu require you to pull out a mylar strip in order to drop developer down where it needs to be. So my guess is that it needs to be pulled all the way out and on the end you will see a little bit of toner. Now alot, but a little on the end. Also the box that it came in should have some directions for installation. Good luck. Please rate this. Thanks.

After changing the black cartridge of epson aculaser c1100, a message flashed: Service Req E511


Welcome to FixYa, the world's largest product support community.

The message E 511: Service Required is commonly due to the Photo Conductor Unit's tabs getting stuck. So the first thing we need to do is to remove the PHoto Conductor Unit. Here are the step to remove the Photo Conductor Unit off of your EPSON Aculaser C1100.

1. Turn the printer on, and open cover B.


2. Raise the yellow lever inside cover B.

3. Remove the photoconductor unit.


4. Check the white tabs on the underside of the photoconductor unit. These are spring-loaded plastic tabs that should depress when you press and release it. If the white tabs no longer spring back you need to replace the photoconductor unit.

After removing or ultimately replacing the photoconductor unit, please follow the step by step giude on how to remove the photoconductor unit in reverse order.

After a few copies are made, black streaks start showing up on the copies and gets worse with each successive copy

for most copier those black streaks are caused by poor cleaning of the Photo Conductor Drum these can be fix by replacing the cleaning blade. after replacing them clean the Photo Conductor Unit and make some test copies.

Error message: replace pcu

I believe its asking you to change the photo conductor unit. From what I can tell there are 2. Theres a black photo conductor and a color photo conductor. If its not telling you which one you should be able to print a supplies status page and you can see which one needs to be replaced. I'm not totally familiar with the machine but the PCU's should be located in the cartridge area. I just checked out our supply catalog and you should be able to order them from any office supply store or Ricoh dealer. Just a heads up..from what I'm looking at the black pcu is pretty reasonable, but the color one is $300 plus! For your sake I hope its the black one that needs replacement! You should be able to verify the error message in your user manual and more than likely find the part number for ordering.

I have a Lexmark E232 printer. It has worked great up until a few days ago. Print quality became poor. I purchased a new toner cartridge Did not help. I purchased a new drum unit. Just installed,...

Blank pages can be caused by a defective printhead assembly, LVPS/HVPS, or controller card.

Blank pages are typically caused by the PC ( photo conductor ) roller not being charged properly.

The first step would be to try a new toner AND photo conductor kit., but since you stated that you have already tried that we can rule that out.

The next most logical unit to replace would be the LVPS/HVPS.( both power supplies are combined in one replaceable unit). The reason I say this is similar to a car with a bad battery. If you try to start it, it may not have enough juice to turn it over, but it tries, and then gets slower and slower. If you wait a few minutes, it still does not start the car, but again it has more charge and then slowly dies. I think your power supply is defective, although not DEAD, and tries to do its job by charging the photo conductor unit, but just unable to complete the task.

Although a possible cause, the printhead would be the last and least likely to cause the problem. USUALLY if the printhead goes bad it results in a service code being generated.

The part number for the card assembly, LVPS/HVPS 110 V, is 56P1818
The part number for the card assembly, LVPS/HVPS 220 V, is 56P1819
The part number for the print assembly, laser/mirror E232, is 56P1812
and the part number for the controller card, is 56P3087

I do not sell parts, and just give you these part numbers for your reference. you can probably search google,ebay, and/or craigslist to get an idea of prices. Then you can at least make an informed decision on what to do as far as "fix it or just chuck it"

I wish you the best... good luck!

Color Photo Conductor Unit

the vertical line that you saw is an indication of either it is normally worn out, or something has caused the scratched, by any material ( PC drum is very sensitive to any material and can easily damaged or scratched any solid and unwanted dirt inside) see you actual meter reading. if it falls on the first thousand copies or print then it might have caused by a scratched, if it falls beyond the PM parts repalcement then there is nothing you can do but to replace this.

sometimes you can swap the colors, by the affected color use the yellow drum unit to the affected drum, the vertical would not that be obvious.
