How to Identify and Fix Common Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

The printer is either low in toner, the density is set too low, or the Economode may be turned on. Remove the toner cartridge and shake it. This will redistribute the toner and often will temporarily solve the problem. However, this usually indicates it is time to install a new cartridge.
If your printouts have incorrect colors, try these solutions: Make sure the paper type setting matches the paper you loaded. Make sure the Black/Grayscale or Grayscale setting is not selected in your printer software. Run a nozzle check to see if any of the print head nozzles are clogged.
Press your printer`s Setup button. Go to System Setup. Choose Print Quality and then Calibrate Color. Choose Calibrate Now and press OK.
If the “Scanner error 2” keeps coming back, you should replace the flatbed scanner assembly. The “Scanner error 2” usually triggers when the scanner`s drive motor fails. Fortunately, replacing the flatbed scanner assembly is not considered difficult.
1: Check Printer Power, Cables, and Paper

Check that the correct paper is properly loaded into the printer and is not jammed. Replacing damaged cables, plugging in loose or disconnected cables, and fixing paper jams as necessary may resolve the issue.

From the File menu, select the Print option. Select the printer from the Printer menu. Expand the drop-down list, and then select Color Options.
Check if the paper that you`re using matches the paper type in your printer setting. Check if the printer is on a flat and stable surface. Most printer models won`t work if it`s tilted in an angle. Clean the print head in case of clogged nozzles.
If your printer is running low on ink, it may start printing blank pages. To check your ink levels, go to your printer`s control panel and select the Ink Levels option. Whenever the ink levels are low, replace the cartridges with new ones. You can also try shaking the cartridge gently to redistribute the ink.
Most printers will stop working when they`re out of paper, ink or toner, or if the unit detects an issue with the ink or toner cartridge. When this occurs, you might receive an error message or notice blinking green or amber lights on your printer.
The paper might not be engaged with the feed rollers. The paper-width guide is pressed against the paper stack too tightly. The paper tray is not completely inserted into the product. The paper settings in the print driver do not match the paper loaded in the paper tray.
For most purposes, and most users, working in RGB should produce the best results. If you want to embed or assign a profile to your file(s) we recommend Adobe RGB 1998. Conventional wisdom holds that you work in RGB for screen-based work, and CMYK for work that will be printed. That is no longer the convention.
Running out of ink

If your printer runs out of ink, obviously the pages will come out blank when you attempt to print out what you need. Most of your HP printers will already have some kind of indicator to let you know that you are running slot. Solution: The solution is a no-brainer. Replace the ink cartridges.
