1. Check Remaining Ink / Toner Levels & Replace Cartridge if Necessary. Before you do anything complicated, make sure that your printer is not running out of ink or toner. You can visually inspect the remaining cartridge levels on your printer.
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.
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.
Ink Cartridge Settings
The cyan and yellow ink cartridges work together to create green in prints. As there isn`t a dedicated green cartridge, you must disable either yellow or cyan to reduce green. After clicking on the “Ink Cartridge Settings” button, you can deselect the “Cyan” or “Yellow” ink cartridge.
Reasons why your HP printer has ink but won`t print
This may seem obvious, but it sometimes happens: first make sure your paper tray has paper in it. Misalignment, clogged printheads, faulty data communication or insufficient ink levels can also be sources of the problem.
Here are the most common causes of a printer printing faded text or images: Low ink or toner levels. Toner sticking to the fuser roller or problems with the transfer roller. Low ink or toner density settings.
CMYK color mode is used for printing.
Your computer monitor uses the RGB model to create colors on the screen, whereas the printer uses the CMYK model to put the colors on paper. Thus, printers cannot replicate all the colors that a monitor does. Also, it is quite challenging to convert on-screen colors to CMYK and replicate them for printing.
HP EasyColor scans documents and automatically adjusts photographic images in . JPEG or . PNG format. Rather than dividing an image into several pieces, HP EasyColor technology enhances the entire image at one time, which results in improved color consistency, sharper details, and faster printing.
Kindly go to Start > Settings > Update and Security > Troubleshoot > Printer > select Run Troubleshooter. You may also check the print settings to ensure that the option for black and white/grayscale is not selected.
Click Start, go to Devices and Printers, right-click on the icon for your printer and select “Printing preferences.” There should be a “Color” tab. Look at that and make sure that “Print in Grayscale” is not selected. Click OK. The figure below is from a different HP printer, buy yours should be similar.
If you print in mostly black, your black cartridge will naturally run out faster than the color cartridges. However, some printers will pull a bit of ink from the color cartridges when you are printing solely in black, just to keep them primed for future use.
HP Photosmart 8750 intermittent serv. stat. stuck
I had this error after the printer sat idle for many months. I thought it was the cartridge drive belt stretching, because it was extremely loose and wouldn’t move the carriage due to slippage. Then I noticed there was a gear belt tensioner to the right side that had some movement. Sure enough, when I shined a flashlight into the ink reservoir, there was a spring that had fallen down inside. Looking at the plastic belt tensioner, it looks as if the spring was held on by a plastic post that had broken off. This is most likely the cause of many of these errors, because the plastic break is very clean and not readily visible, (a design flaw in my opinion). Rather than trying to replace the part, I am going to try tapping a hole in the plastic and inserting a machine screw that can hold the tension spring in place. It also looks like the metal notch for the right hand loop of the spring, would not prevent the spring from slipping off at some point, so using a metal file to enlarge the notch may be necessary. If you’re lucky, your spring may have just popped off and is inside the ink reservoir. This may be one reason why the printer was discontinued so soon. One lousy five dollar part makes the whole printer worthless… I use this this printer primarily because it is easy to clean the heads by removing the carts, instead of having to disassemble the whole damn thing, as in ink tank designs. It makes beautiful 13×19 prints with better color accuracy than my Vivera 6 ink printer.
