We suggest you contact 'Parts Here' as they provide most parts for the C5280 printer, including carriage assembly parts, along with the C5280 service manual:

C5280 CONTACT CLEANING / SERVICE TEST DIAGNOSTICS:
A. Ensure BOTH carriage/flex cables and BOTH ink cartridge contacts are thoroughly clean before proceeding - refer to Inkjet411's support page:
http://inkjet411.com/?page_id=1519
B. Print Self Test Page:
1. Press and hold the CANCEL button.
2. Press the COLOR COPY button. Release both buttons.
3. The self test page should print. The printed pattern will verify printer is generally functional
--- The self test page is a 'forced' test print whether the ink cartridges are good or bad. Inspect color bars to verify proper nozzle/jetting health. If normal/regular printing is still not permitted then the problem is with either one, or both, of the ink cartridges. Activate Tap 41 test to confirm which cartridge is causing the issue.
C. Validate the cartridge's electrical health by running the 'Tap 41' diagnostics test. Refer to video procedure or .pdf document at the following links on how to activate and read the service test report:
http://inkjet411.com/?page_id=536
1. Load Letter/A4-size paper into paper feed tray.
2. If any lights are blinking, first press Cancel to attempt to clear.
3. Press and HOLD the Cancel button, press Ok button once.
4. At 'Mfg Commands' menu, click Right Arrow once until 'uiaux service' menu is displayed.
5. At 'uiaux service' menu, click the Right Arrow until Special Reports menu is displayed.
6. Select Ok, then click Right Arrow until the 'print-mech button tap' menu is displayed.
7. Select Ok (Code = 0 will be displayed); click and hold Right Arrow until 'code = 41' is displayed. Use the Left Arrow if you need to decrease numerical count.
8. Select Ok. Within one minute the Tap 41 diagnostic test report should be initiated and print (whether ink cartridges are good or not, i.e. this is a forced print test). See following 4 paragraphs (or video) on how to interpret diagnostic report.....
--- Providing the color cartridge is partially functioning the Tap 41 diagnostic test print will be printed (this is a forced service print test which is mainly used for the evaluation of ink cartridge electrical health). A good HP 75/75XL color cartridge should display 600 good nozzles, while a good HP 74/74XL black ink cartridge should show 672 good nozzles. If the results yield anything different then the ink cartridge is likely damaged and will need to be replaced. Refer to video on how to read the printout.
---- If the printer attempts to print the diagnostic test pattern (1 page) then the printer is generally considered operational and functional, if nothing is printed, but the printer attempts to print the pattern, then the tri-color ink cartridge is either empty, clogged or severely electrically damaged (black ink cartridge is not used). You can remove the tri-color cartridge, reactivate the tap 41 test and the printer will print the diagnostic test print in black ink.
You can also test general printer performance by running the 'Tap 10' diagnostic test, use same procedure above and enter "code = 10". Both the 'Tap 41' and 'Tap 10' tests are 'forced print tests' - the printer will make every attempt to print the pattern whether the ink cartridges are good or bad...the patterns should be utilized to diagnose cartridge health. If 'regular' printing is still not possible then one or both of the ink cartridges is damaged.
NOTE: If you need to purchase a new ink cartridge(s) and are trying to cut costs, we suggest you try a remanufactured ink cartridge from
http://www.inkplicity.com/ as their ink cartridges typically have the lowest cost in the USA, have a high reliability rating, come with a 1-year warranty and provide free shipping for all orders above $20 (available for US Residents only).
