Printer not printing red colour

[Lee1972]

Hi.

I am having problems with the printer only printing three colours. I have performed all the nessesary checks on the print heads etc with all checks returning as good.

I am now wondering if the pipe leading from the cartridge to the print head is blocked.

Is it possible to clear any blockage and if so can someone post a guide to dissasemble the printer and perform maintenance on it to to get the red colour working again.

Many thanks and kind regards.

Welcome to the HP Forums, this is a great location to get assistance! I read your post and see that your HP Officejet Pro K8600 Printer is not printing in red. I would like to help you resolve this issue. 

Increase the print quality mode

1. In the application you are printing from, click File, then Print.

2. Make sure the printer is selected, then click Properties.

3. Select the Features tab.

4. In the Print Quality area, chose the next higher quality setting (if the current setting is Draft, choose Normal. If the current setting is Normal, choose Best).

Clean the printheads.

1. Make sure the printer is loaded with unused white paper.

2. Open the printer Toolbox and select the Services tab.

3. Click Clean Printheads. A Clean Printheads window opens. Click the Clean button.

Align the printheads.

1. Make sure the printer is loaded with unused white paper.

2. Open the printer Toolbox and select the Services tab.

3. Click Align Printheads. The Align Printheads window opens. Click Align.

4. The printer prints an alignment page. The lines in the patterns should appear to be straight. Click OK when the page finishes printing.

Calibrate the linefeed.

1. Make sure the printer is loaded with unused white paper.

2. Open the printer Toolbox and select the Services tab.
