Photosmart C5180 Won't Print Magenta

[Skipper5833]

I found a FIX for this problem on my printer and would like the community to be aware.

SYMPTOM:

Printer will not print either Magenta or Light Magenta (standard 'Test Page')

However, both colors print when the "Extended Self Test Diagnostic Page" is printed.

(Magenta prints as 'Lavender')

SOLUTION:

"Reset the Control Board" as follows:

1. Disassemble the right side panel to access the control PWB

2. Remove the control PWB (ensure you have grounded your body before touching the board)

3. Locate the 3 volt Battery 

4. Remove the battery, confirm voltage using VOM, and reinstall battery

5. Reassemble the unit

Additionally, I did the following, just to be safe:

a) remove all cartridges before powering up

b) power up

c) install cartridges

This cleared the fault and now the printer works fine
