I have an Epson 7800 that has gotten light use over the years and was printing perfectly. Ignoring its pleads to power clean for several months, I finally relented and went through the process Saturday morning. At first, the light cyan would not print so I went through the normal cleaning routine with the utility first then PiezoFlushing the blade, the cap and finally letting the heads sit overnight on a paper towel drenched with the stuff. This had zero effect, so I sent it through 3 more power flushes. This made matters much much worse. Now, only yellow is printing correctly.
I scanned the test page to attach but the forum system won’t let me upload it.
The dampers, wiper and cap were replaced two years ago but again, this printer get very light use. Compass Micro will not commit but suspects a pump cap assy. Any ideas?
