Parts inside your printer are near the end of their service life. See your printer documentation Solution
I have had a R300M for a while now and had a few cartridges in it. (Mostly Compatible Cartridges not OEM) Recently a message came up on the screen 'parts inside your printer are at the end of their life' and the printer refused to work! After searching the web it appears to be a waste ink counter, but I could not find any info on resetting it. Tried pressing different combinations of buttons on the printer and success. (Found Ink counter reset)
Press and hold 'stop' 'maintenance'(ink button) and 'power' buttons for about 10 seconds,(while printer is on) a message will come up on the screen saying counter is reset and to turn off.
Thats it, turned my printer back on, and all works fine again.
I hope this helps R300/R300M owners out!(Also I have email into Epson Support, can't wait to hear what they say the problem is for the fix!)
Service Required Parts Inside your printer is at the end of service life.This message refers to the ink pads, which are actually a number of porous pads in the printer that collect, distribute, and very importantly contain the ink that is not used on printed pages. Ink is collected by these pads during the initial setup of the product, during cleaning cycles and when printing borderless photographs. Most users will not receive this message before the printer is replaced for other reasons. Some high volume users or those who use the printer for many years may receive this message about ink pads before other components reach the end of their usable live.
The best solution that we can advice regardding this error message are the following: 1. Download the Epson Ink Pad Reset Utility athttp://www.epson.com/ipr
