Printer Error 034503 Troubleshooting and Resolution
Background
Hi, we have a WF 7210 with chipless firmware but all of a sudden, after we ran a head clean, we can't use the printer anymore. It will start up like normal and during the start up we get a error saying the cartridge cover isn't closed (We took the cartridge cover off and wasn't a issue in the past) then when we continue we will get error '034503'. This happened to our old Epson WF 7210 chipless but we ran a head clean via WIC reset. On this printer we only ran head cleans using the on board screen as we thought the old printer was broken by WIC.
Troubleshooting Steps Taken
We have tried:
- Cleaning the print head service station
- Checking for any jammed gears
- Removed and cleaned the clear wheel on the front left
- Checked and reconnected wires and sensors
- Check for any obstructions in the carriage movement
Resolution
- We gave it one last ditch effort before we left work for the night a sprayed loads of cleaning solution into the print head service station, then cleaned it off the little pads where the ink is dumped.
- Then when we rebooted the printer it worked fine and recommended we did a print nozzle check pattern, which came out fine.
- We will keep updating this post in case anyone seems to run into the same issue, just follow this with caution as we don't know much about printers and are following our guts.
- It is recommended to check for hardware issues such as broken belts, obstructions in the carriage movement, and lubrication of guides for smooth movement.
- In the end, we opted for a new printer, the ET 14000 for dye sub printing as we couldn't find a cheap replacement for the damaged belt on the WF 7210.
Follow-Up
We will try this on the other printer and come back to let anyone know if this is the solution. Feel free to share your experience and solutions to this issue. Thank you.
