An inkjet printer printing lines or missing lines on printouts are caused when the printer cartridges or the cartridge carriage which contains the print head becomes dirty or damaged.
In the Print & Scan or Printers & Scanners window, select your printer, and then click Options & Supplies. Click Utility, and then click Open Printer Utility. HP Utility opens. Click Align .
White streaking through the printout or an entire missing color both indicate an empty cartridge. If the cartridge is depleted of one color, it needs to be replaced. Each color is necessary to create the colors used in day-to-day printing.
If your printouts are faint or have gaps, try these solutions: Clean the print head. The ink cartridges may be old or low on ink, and you may need to replace them. Make sure the paper type setting matches the type of paper you loaded.
Partial prints are a common issue with printers and there are several main reasons it can occur: Problem with the print spooler (on Windows PCs) Overload of the GPU on later model Macs. Dodgy USB cord.
The printer printing every other line of a document would generally be caused by a connection issue between the cartridge and printer or a defective cartridge. The troubleshooting steps in the document here may help resolve this issue.
What Is Banding? Banding is a defect in inkjet printing that will appear as horizontal or vertical lines, streaks or bands in the printed output. Everyone will eventually experience some type of banding with their inkjet printer.
Faint, streaky or spotty prints are all common signs of a clog but a simple cleaning can usually get your HP ink cartridges working again. Printheads clog due to infrequent cartridge use. If you regularly go a few weeks without printing, your cartridges will eventually dry out and need to be replaced.
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.
