Print head replacement means you need to get a new print head. Putting the old one back in is not what your plotter needs.

Not normally but the black print head nozzles maybe blocked.
Inkjet printers need to be used frequently to prevent ink drying out and blocking the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages, then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer than replace the print head.

Most of the time its the print head, this is very costly. The print head tends to clog if you don't print often. Try to print at least a test print once or twice a week.

Did you replace the tri-colour ink-cartridge, or did you replace the print-head mechanism?

Are you sure that the CYAN part of the ink-cartridge is not empty?

This document provides information about replacing the print cartridge for the HP LaserJet 1010 printer series, including life expectancy and replacement instructions. Print cartridge life expectancy The life of the print cartridge depends on the amount of toner that your print jobs require. When printing text on letter/A4-size paper at five percent coverage, the print cartridge lasts an average of 2,000 pages. This assumes that you set the print density to three and disable EconoMode. (These are the default settings.) See Ordering supplies for information on ordering replacement print cartridges. Changing the print cartridge Follow the below instructions to change the print cartridge:

1. Open the print cartridge door, and remove the old print cartridge. See the recycling information inside the print cartridge box. Figure 1: Removing old print cartridge CAUTION: To prevent damage, do not expose the print cartridge to light. Cover it with a piece of paper.
2. Remove the new print cartridge from the packaging, and gently shake it from side to side to distribute the toner evenly inside the cartridge. Figure 2: Gently shaking new print cartridge
3. Pull the tab until all the tape is removed from the print cartridge. Put the tab in the print cartridge box to return for recycling. Figure 3: Removing tape from print cartridge
4. Insert the print cartridge in the printer, making sure that the print cartridge is in position. Close the print cartridge door. Figure 4: Inserting new print cartridge

Hi,
This happend with some printer models that both cartirdge should be there for proper printing.in your case this may be due to that some printing you do may be in gray scale printing that type of printing use color cartridge for printing.thats why your color cartridge get consumed.so pls replace color cartridge or refiel it.

I'm more familiar with HP printers, but it sounds like a fuser is bad. The fuser effects print quality as well. If you've replaced the toner, as you have.

You say you replaced the cartridge but did you replace the print head. If you fully lift the cartridge cover you will see a row of print heads. The Cyan print head is C4811A. Try replacing this.

If you feel lucky you can run the print head cleaner diagnostics. The print head may simply be dirty or clogged.

The only way to corret the problem is to replase the fixing unit... That is what the L4 is refering to. It is not reading the correct tempurture..
