Its probably due to the roller, which are supposed to be changed every so often anyway.

With use, the rollers become scored/worn in places. The excess toner powder that is not used in the printing process is removed by a rubber blade. When the roller becomes worn it isn't wiped clean by the blade ... and you get that characteristic black line down the paper.

Change the roller. You'll probably pick one up on ebay.

Tip

When u print if u r getting the Horizontal or vertical line then follow these...


If the print is a dismal gray rather than a sharp black, you are probably almost out of toner. This can manifest itself evenly across the entire page or in splotches or stripes, depending on the printer.
Sometimes you can wring a little bit more out of a toner cartridge by taking it out and gently shaking it from side to side (never up and down, as toner can spill out). You can also try turning up the printer’s contrast adjustment, if it has such a knob (usually on the back side if it exists). Faded print can also result from a dirty corona wire, because a dirty wire inhibits a full electrical charge from being passed.
If the printouts are consistently varied in density, and you have to frequently remove the toner cartridge and shake it to redistribute the toner inside it, make sure the printer is sitting on an even, flat surface.
Horizontal black lines
A horizontal black line on the printout is probably the result of a dirty or damaged roller. There are lots of rollers in the printer, and you can use the space between the lines on the page to determine which roller is causing the problem. Measure the distance between the errant black lines on the page and then use Table A to determine which part might be causing the problem. Table A
Distance between lines
Faulty part
0.5”
Registration assembly
1.5”
Upper registration roller
1.75”
Lower registration roller
2.0”
Toner cartridge developer roller
2.56”
Lower fusing assembly roller
3.16”
Upper fusing assembly roller
3.75”
Toner cartridge photo drum
Regularly spaced splotches
If there are evenly spaced black spots but they don’t extend all the way across the page, the problem is probably a scratch or flaw in the drum or a build-up of toner on the fusing roller. If the spots are less than three inches apart vertically, it’s probably the drum, because the drum has a larger diameter than the fusing roller.
Vertical black line on edge of page
This can indicate an almost empty or faulty toner cartridge or (less frequently) some spilled toner inside the printer.

How to configure printhead alignment


Hi there, Aligning the Print Head

If ruled lines are misaligned or a printout is unsatisfactory,Print Head Alignment is required.

Steps for Aligning the Print Head.
1) Press [Menu] repeatedly until [Maintenance] appears.
2) Press [Maintenance] repeatedly until <P> appears.

3) Press [Black] or [Color].
The machine print the head alignment sheet.

4) Beginning from column A on the printout, enter checkmarks in the patterns that have the most solid image.

5) Load the checked sheet on the Platen Glass.
When loading the checked sheet, place the front side down, and align the upper left corner of the sheet with the alignment mark on the lower right corner of the Platen Glass.

6) Press [Maintenance] repeatedly until <U> appears,

7) Press [Black] or [Color].
The machine scans the pattern and aligns the Print Head automatically.
Note : If you select <L>in step 2, the machine prints the current Print Head Alignment setting.

Hope this help.
Have a good day.

Line on printout from scans and copies


Clean the glass AGAIN. I had this issue for weeks. Drove me NUTTTTS! Because I to cleaned the glass. But guess what... not well enough. On your glass there is a tiny .. maybe the tiniest of tiny.....speck somewhere. that causes this line. Trust me I did everything you did and I just knew it was the drum or something. But it wasn't. Sure fire test. Have someone fax you something directly to the machine. (you need something that doesn't pass over the glass) If it prints out fine .. no line... there is a speck on your glass!!! And anything copied, faxed or scanned from your unit will have that line. Ofcourse you have already done half the test yourself if you print something from your computer and dont see the line. Because a print would not pass over the glass either.

No black when printing color


Dear Sir,

You are getting black lines in green color,and apperence of parallel light and dark lines because your colour catridge is almost empty.So solution is replace the catridge and take a printout. There is no proplem with a printer. i think it solves your problem.


good luck

Red and blue lines across printouts


open printing preferences and click on maintenance. Run the print head alignment utility. Sometimes this will remove the horizontal banding. I had this same problem and had to uninstall the printer and reinstall just like it was new, running the alignment feature before it was corrected. Worked ok for a few days then started again. I assumed that the printhead is bad. To costly to repair and bought a new printer.

When I change the black ink cartridge, the alignment page and instruction page are printing out fine. When I place the alignment page on the glass as instructed and press 'ENTER', the printer gives a...


I just had the same issue (align page not detected).

We had just re-installed the empty color cartridge back into the printer (long story but basically we knew we could only print B/W).

The align page printout had a lot of empty spaces around the black lines. This is apparently where the color lines are supposed to print.

Without those color lines, the printer would not detect the align page as color is part of the alignment being done.

Since we only wanted black printouts, I pressed 'cancel' to stop the alignment process, and now we just hit the Black copy button and ignore the alignment prompt on the printer window.

The HP site (enter psc750 in product window) has some helpful ideas as to what the problem might also be. It could be the shipping tape is still on the new cartridge (and preventing the black or color from printing on the align sheets) etc.

Black not printing about every 3rd line


You have the classic single nozzle failure it appears. You say you have done a nozzle check. This should reveal that one of the black nozzles is not working i.e. there is a single gap in your nozzle check printout for the black nozzles. Now, this may be due to a blocked nozzle. Try the following print head soak process.

Turn the printer on, and as soon as the print head moves pull the power cord out of the back, or turn the printer off at the mains. You may now carefully move the print head by hand over to the left hand side out of the way. Look inside the print head parking area on the right and you will see a small rubber cup that comes up to cover the print nozzles when the head is parked (to stop it drying out). Use a syringe or dropper to fill this cup with head cleaning fluid or distilled water. DO NOT USE TAP WATER. Carefully push the print head fully into its parking position so that the cup full of fluid comes up over the print head. Leave this for at least 24 hours, then try a head clean again. If still nothing, report back
