Tried the cleaning routines? Repeatedly? If it's a Canon you can remove/clean the printhead. Try new cartridges.

Hp laserjet 4200 printer printing vertcal faint line


Check the cartridge and make sure that there is no scratch on any of the cylinder. If any cylinder is scratched you will need to replace it. Perform a cleaning with isopropylalcohol in these cylinders if they are not dirty and test the printer. If the problem persists, probably the fuser film is damaged and will need to replace it. If the line still continues to appear, the laser scanner may be dirty or damaged. Try to clean it or replace it.

My printer won't print. we installed new ink and the callibration test won;t even print. all you can see is faint lines.


how long was your printer out of ink before you replaced it? could be clogged from old ink preventing the ink from flowing freely.

Hi, my Epson 2100 is printing with faint lines at regular intervals right across the page. I've done various alignment tests and cleaning tests but can't seem to clear the lines. Any advice much...


Are your alignment tests show good results? If they are, try head cleaning 3 consecutive times without printing nozzle checks. After 3 head cleanings do the nozzle check. If problem persists try printing at BEST PHOTO or whatever is the slowest print setting for your printer. Good luck!

Faint & White Lines in Printer Head Alignment


This sounds like you are using either a refilled cartridge or an after market cartridge and the ink is clogging the print nozzle. To clear the problem you need to insert an OEM cartridge, run the deep nozzle cleaning utiliity, alignment utility. This should clear up the problem with the spotty printout.
Let me know if this solves your problem otherwise we can explore other solutiions.
Please rate this solution. Thanks.

A faint line shows up down the middle of the page, when printing a photo


from cnet review of the product

  • Unfortunately, as with the Z1420, fast print speeds come at the cost of print quality with the Z1300. Black text prints, though nicely dark, were beset by obvious jaggedness. The color graphics print had a slightly faded look to it and color blocks showed graininess and faint horizontal striations. Barcode-style patterns were muddled, too. For our tests, we printed color 4x6 photos with the standard black and tricolor cartridges, as Lexmark did not include photo ink tanks with the test unit. The colors were dull, details were hazy, and again, the entire print was marred by graininess and faint horizontal lines. That said, nobody buys a $25 printer to print photos for framing or to create displays for a classroom science project. A $25 printer is a convenience item for occasional reference prints, and as such, the Z1300 does its job.

Faint red line across page when making color copies or printing in color from computer


Some possibilities are:

1) Dirt on the glass, dirt on the glass strip for the doc feeder, or dust on the mirrors. This would be the case if the line only showed when copying and not printing.

2) Toner dropped onto the charge sawtooth.
This may be possible if the line is intermittent and only showed up for 1 or 2 colors.
Open the front door and remove the waste toner box. To the left of each drum there is a green organ-stop type stem. Pull and reinsert each stem. You will hear a zipping noise. These are your charge scrubbers.
This may be not as likely if the line shows up in the same place on all 4 colors

3) Toner or dust on the lens
This may be possible if the line is intermittent and only showed up for 1 or 2 colors.
In the area where the waste toner box goes, look for a grey stick with a white cushion on the end. This is your lens scrubber. Look in the area under the charge scrubber on each drum cartridge for a gap. Insert the scrubber cushion side down into the gap and run it forward and back to clean the lens.
This may be not as likely if the line shows up in the same place on all 4 colors

4) Transfer belt blade not cleaning
This is best handled by a service tech since the mylar belt is very fragile. The squeegee blade that cleans the transfer belt between copies is missing a spot. The blade needs to be taken off the belt, cleaned and repowdered. Recently, Sharp made changes to the composition and thickness of the mylar in the transfer belts. Overpowdering the blade or belt when it was changed may cause improper cleaning of the belt creating lines across the copies. Often the condition clears up after a couple of days as the gap between the blade and belt is sealed.
This is most likely the cause as the line shows up in the same area for more than 1 color.

5) Transfer belt and/or blade is worn out
If the belt is worn the blade must be replaced but not vice versa.

6) Clogged waste augers in the drum cartridges.
Waste toner may cake up in the drum cartridge and knock loose on the drum.

It may be time for full maintenance on the machine.

Printing faint lines with fine corresponding creases on drum


You probably can not repair it. I will say this though, be careful to get the right labels for it.
