1 Check the Copyboard Cover, Copyboard Glass, and Standard White Plate

  • If any of these parts is soiled, clean it with a moist cloth. If scratches are found, replace it.

2. Checking the Charging Assemblies

  • a. Check each charging assembly for dirt and a fault in its charging wire/charging brush (scratches, deformation).
  • b. Clean the charging wire, grid wire, and shielding plate of each charging assembly. (Dry wipe the part with lint-free paper; then, clean it with alcohol. If dirt cannot be removed, replace it.)
  • c. Check the height of each charging wire.
  • d. Check to see each charging assembly is properly set.
  • e. Check the charging spring (especially of the separation charging assembly) for rusting.

3. Checking the Developing Assembly
  • a. Check to make sure that the rolls on both ends of the developing assembly are in contact with the photosensitive drum.
  • b. Check to make sure that the surface of the developing cylinder is coated with a uniform layer of toner.

HP5610 - HORIZONTAL STREAKS ON COPY & SCAN


Yep, only when you use the document feeder? If so, lift the document feeder lid, get a clean lint-free cloth and some glass cleaner. Apply some of the cleaner to the cloth then, clean the small of the two glass areas. That is the only section that reads documents fed through the document feeder! Run a blank sheet of paper through the document feeder first before cleaning and make a copy. Take the copy and, if there is a line (or lines)on the copy, place it on the larger document glass face up.Follow the line to the smaller glass. The dot of debris will usually be there. If you don't see anything wrong, clean the glass anyway. Run another blank sheet through the document feeder. Check that copy. If the lines are gone...Viola! you have solved the problem. It it has not and you've cleaned it more than once, the debris is on the mirrors under the glass and a technician will need to come out, remove the glass and carefully clean the optics/mirrors.
Good Luck.

What setting to do , if i insert thick paper or plastic sheet to be printed


make and model of machine please? it depends on if you are printing or copying to the special media. there are settings on the control panel as well as in the print driver to select special media types. beware of "plastic sheets" and any coated paper if you are using a laser device that has a fusing unit that heats the media to fuse the toner. using the wrong media can cause major damage.

When printing black dots appear chaotic, over the entire sheet of paper. What to do?


If the black dots appear on every sheet of paper it could be the fuser unit is wearing out or the drum unit. The way to check that is to stop a print half way through and remove the paper. If they are not there before the fuser unit but after it then it will be the fuser. Or if they are there before the fuser unit it will be the drum unit. If it they only appear specfic to one source then it is likely to be the source of the document. IE copying - check the optical area (scan glass etc). If on incoming Faxes it may well be the sender that has the problem and is just transmitting them to you. Hope this helps.

Bizhub C652 has horizontal lines.


its important to find out whether the \'lines\' are in scan direction/ or only through Radf or only from scan glass,

if the lines are only showing when documents are fed throught the Radf, then the problem lies with the document scan plate( left of the main glass platen (about 2" in width)) or with the scan plate blade cleaner

if the lines ONLY appear when copying from the Glass then the issue lies within the optics (probably nothing more than a clean will be needed)

another question would be to ask if the lines are solid (black line overprinting image) or if they are \'missing\' lines where the image has failed to copy, sometimes it can be hard to work out which side the fault lies,so try shaded greys as a copy original .

if the scan lines are appearing on both Radf and Glassplatten ,mode then the issue may be dirty optics/ccd sensor or it could e an indication of the ccd failing or image control pwb in error while interpreting the image file.

what to do

1) place a grey sheet of paper in the Radf and have the copier photocopy both sides of the original and print to single sided sheets ( so the printer turns the original over to complete the task)

observe the result.

2) have the copier photocopy directly from the platten glass- single sided.

observe the result.

ckeck to see if the error has appeared on both sets of prints ,

if the error has only appeared in the first set of prints then the issue may be a tiny DOT on the slit glass (left of platten) - a dot on this glass will indeed appear as a Line as the original is scanned across the glass.

hhope thhis helps

Black dots/blotches on the sides of printed sheets - whats is the cause and how t to fix it


If you have random blotches on both sides of the sheet, your printer probably needs cleaning, especially in the fuser section. If the fuser is difficult to get at, here's a good cheat developed for HP LaserJet 6 printers: Use a basic graphics program such as Microsoft Paint to draw three solid black rectangles about 2.5" top to bottom, going all the way across the paper (the space in between is not critical - the key is that you go as close to edge-to-edge as you can get). Print out this sheet.

Put the sheet back in the paper tray so it will print on the blank side (usually printed side up). Open up a quick text processor (Notepad in Windows). Type a single space, then print (some text editors won't print a document with no data in it). Dirt in the fuser will get stuck to the black areas on your cleaning sheet. Test your work by printing another copy of " ". Repeat with a new cleaning sheet if necessary.

When printing the sheet of paper has 3 dots on the


Yes this could be the drum.

You could remove the drum and carefully look for the pattern of dots etc that you are getting on the page but on the drum surface.

I would suggest replacing the drum 1st and retrying.

If the black lines are just down one edge then the fuser could be to blame for the black marks but without being able to see the page i cant tell. The drum is certainly my 1st suspect and is easy for you to try.

How do I clean white or black spots on printed documents? Description: First make 10 to 15 copies of a blank, white sheet of paper.
If you still see the spots on printed documents after making multiple copies, clean the drum unit as follows:

  1. Remove the drum unit and toner cartridge assembly, and then remove the toner cartridge from the drum unit.
  2. Position the print sample in front of the drum unit so you will know the exact position on the drum that is causing the poor print.
  3. all-ug-19.gif
  4. Turn the black gear on the drum as you check the surface of the OPC drum.
    The OPC drum is photosensitive so do not touch it with your fingers.
  5. all-ug-20.gif
  6. When you find the substance on the drum surface that matches the print sample, gently dab the surface of the OPC drum with a cotton swab that is lightly dampened with isopropyl alcohol.
  7. Note
      • Do not use a scrubbing or wiping motion because this might damage the drum.
        all-ug-21.gif
      • Do not try to clean the surface of the OPC drum with a sharp object, such as a ball-point pen, because this might cause permanent damage to the drum unit.
  8. If the print quality still has not improved you need to install a new drum.

Error code 5100


Here's what worked for me in solving this error code 5100 problem. Not only was I unable to print anything because I kept getting that code, but there was a thunking sound when the carriage stopped moving, and every time I turned the machine on it was feeding through one sheet of blank paper. I was about to go out and buy a new printer of a different brand because the Canon was unusable.
Then, fooling around with the machine's menu and settings buttons, I came across an option, I think it was in the Maintenance menu, to Restore Factory Settings. I chose that option and it asked me again if I wanted to restore the original factory settings, Yes or No. I said Yes, and immediately the printer started behaving itself. No more 5100, no more funny noises, no more blanks sheets of paper. It is back to its old self again.
That still doesn't solve the problem of spending a fortune to buy ink cartridges, but I just hooked up my old Panasonic 24-pin dot matrix printer to the printer port of my CPU (a ribbon lasts me a year and costs less than $15), and the Canon to another port, so now I can print the day-to-day stuff on the cheap dot matrix and use the Canon for the important stuff.
I don't know if restoring the factory settings will work for you, but it was the solution in my case. Hope it helps you out.
