Also the Pro-1000 has a densitometer for a reason. I've been through the terrible inability of Epson to restore my R2880 when it needed service and they admit they are unable to do it in North America and possibly most other places. Their authorized techs did not even know about that step nor did they understand it.
The issue is REAL, I've been down that road. I've seen the results of purchasing Epson refurbs and did not understand why they did not print consistently from unit to unit until I dug deeper and ran into the issue with my 2880. Back in the day, Epson actually outlined one difference between the R1800 and the Pro-2400. The Pro line was individually trimmed to meet specs.
My P800 developed a dead cyan nozzle and while not viewable in most prints is now a disadvantaged machine. Nozzles that die is a real issue not theoretical. If my Pro-1000 had a deficient printhead and thankfully it has redundant nozzles, I would simply pop in a new printhead and let the machine recalibrate itself. The only requirement I need is to keep stock of the photopaper I stored in memory in the printer. Else, I create a calibration setting with the media I was using and store it away. That way, the ICC I created with that media is immediately perfectly valid when the machine is restored.
