Troubleshooting an Epson R1800 That's No Longer Printing

If you're facing issues with your Epson R1800 printer and it's no longer printing as it should, you're not alone. In this tech overview, we'll dive into a discussion from a user who encountered a similar problem and explore potential solutions and insights shared by the community.

Printer Drying Out Issue

The user mentioned that they travel frequently, leaving their printer unused for extended periods. This can lead to common problems with inkjet printers, as the ink can dry out and clog the printhead nozzles over time. Usually, a simple head cleaning and some wasted ink can revive the printer. However, in this case, the user faced persistent issues.

Attempted Cleaning with Simple Green

To tackle the issue, the user attempted a head cleaning method using Simple Green on a paper towel placed under the printhead overnight. This technique is often used to loosen dried ink or gunk on the printhead surface. However, it didn't yield the expected results, and the printer continued to print only a small amount from a few nozzles.

More Drastic Measures

The user then decided to take more drastic measures by removing the printhead and soaking it in an alcohol and water solution. This approach is effective in breaking down dried ink residues. After a night of soaking, they dried the printhead and carefully removed any remaining ink.

Additional Steps Taken

To encourage ink flow, the user removed the plugs from the ink cartridges, allowing gravity to assist in pulling ink back into the printhead and manifold. After a few hours, they powered up the printer but encountered an issue where the print head was unresponsive.

Community Assistance

Seeking guidance, the user turned to an online forum for assistance. A fellow member suggested that the problem might be related to a printhead issue, a defective driver circuit on the motherboard, or a problem with the flat cable connection to the printhead.

Service Manual Search

The user expressed interest in obtaining a service manual for their Epson R1800 to diagnose and potentially resolve the issue. Another forum member recommended exploring free sources and checking for a broken or missing contact at the flat cable connection, which could be disabling the firing of the nozzles. They also mentioned the possibility of a blown fuse on the controller board or a chip failure after 20 years of use.

Next Steps

In situations like these, finding a service manual can be a valuable resource to troubleshoot and diagnose printer issues accurately. It can provide step-by-step instructions for disassembly, troubleshooting, and potential solutions.

While the user expressed interest in finding an affordable replacement printhead, it's essential to determine if this is indeed the root cause of the problem before making a purchase. Careful diagnosis, as suggested by the community members, can help save both time and money.
