How to Identify and Fix Common Problems ?

The streaks or lines might be caused due to low ink levels in one or both ink cartridges. Check the ink levels using the HP Toolbox to determine if the ink cartridges are low on ink and need to be replaced.
Streaks and unwanted lines could mean that the printer heads are out of alignment. There`s an alignment tool in the printer`s control panel. If that`s not the issue then the printer is dirty. Printer ink stripes may appear along the edges of the paper, which means there`s ink on the rollers and other parts.
A printer printing lines on the page are normally caused by a blocked, dirty, or damaged print head. Blocked ink cartridge nozzles, or not removing protective seals correctly when you installed a new ink cartridge can also cause missing lines of print.
Streaking is usually caused by a worn out drum unit or spent toner cartridge. Drum units are a consumable and only need to be replaced after the use of 3 or 4 toners. Not all printers use a separate toner and drum unit.
For cleaning, HP recommends using HP Equipment Cleaning Wipes, but you can use an HP-approved lint-free wipe and deionized or distilled water. Note: If dark spots appear on back side of prints, clean drum screen. Note: If minilab prints more than 2000 prints each day, clean drum screen up to twice daily.
When your printer leaves black lines, the lines indicate that there are excess toner powders on the rollers or transfer belt within the printer. As the paper is moved along by the rollers and transfer belt, any excess powder left on them can result in lines being left on the paper.
There are four primary causes for horizontal banding on prints from inkjet printers, (1) nozzle clogs, (2) mis-aligned print heads, (3) low quality print settings (4) incorrect paper thickness settings. Below we will describe each of these causes for horizontal banding as well as ways to try and fix them.
Streaks on your print jobs are a result of your copier glass being dirty. “Dirt” is created by fingerprints, dust, and other forms collected through usage. Often this will be detected by your device before streaks begin to appear, and a display will read that the glass needs to be cleaned.

lexmark C544 prints yellow streaks
ANSWER : Are the streaks repeating defects or does it run top-down on the right or left side of the paper ?If you have a vertical yellow shade on the paper, it’s probaly the yellow developer unit which causes the problem. You then can either replace the developer only or (depending on the total number of pages printed, check the statistics !) the complete imaging kit which consists of all four developers and the imaging basket with the Photoconductors.If you see a repeating defect, you should at first print out the print defects page (menue\reports\print defects). Compare the yellow streaks with the printed scales. Above the scales it tells you which component should be changed.

Print Quality Issue (Streaks and Ghosting)
ANSWER : Streaks are mostly caused by internal drum wiper blades that clean left over toner off the drum to prepare it for a new image. Ghosting is caused by a leftover image on the drum. The 6 inches that you mention would be the circumference of the part that is causing it. Fusers will never cause either problem.

Permanent Streaking
ANSWER : First off, there is no transfer roller. It’s a transfer belt. There really isn’t any way for toner to clump to it. The most that could happen would be a very thin layer of toner. I’m kind of under the impression that your tech services guy is clueless and knows nothing about printers. It wouldn’t be the first time I’ve encountered someone like that.

Blank vertical streak
ANSWER : That would be something blocking the laser light. There is a laser unit at the top. It shoots out a beam of laser light that reflects off of a mirror at the top front of the printer and down into the slot at the top of the toner cartridge. Anything that is in the path of that beam will result in a blank area at that part of the page. Just look closely at the top of the cartridge and up into the slot that corresponds with the slot on top of the cartridge.
