Resetting the counter without addressing the physical pad is temporary. If you reset multiple times without cleaning, ink will eventually leak.
Before running the adjustment program, ensure the following steps are taken to avoid computer issues:
The Epson L121 uses a non-replaceable waste ink pad (a sponge) inside the printer to capture ink flushed during cleaning cycles.

, like many inkjet printers, cleans its printheads by sucking ink through them. This waste ink is stored in pads at the bottom of the printer. The printer calculates the amount of waste ink generated based on the number of prints and cleanings. When this calculated amount reaches the limit, the firmware locks the printer to prevent physical leakage. Troubleshooting Common Issues
