Epson Stylus Photo R200 – flashing red lights
ANSWER : The R800 will flash the ink and paper lights alternately when the ink pads are assumed to be full from extensive head cleaning. Sometimes, if not always, the head will lock into place on the right side above the ink head cleaning sponges that release ink to the lower ink pads.To correct the problem you need to clean the sponge area, I use cotton swabs. If the head is locked to need to release the carriage lock with a screwdriver. This will require removing the cover, but not necessarily the bottom of the unit.There is a 179 page service manual available for download for $16.50. There are free downloads of this manual, but usually are missing the 100 pages.You can remove the cover by:1. Remove the three screws on the rear housing (One to the left of the power plug, one on the opposite side and one in the lower middle bottom.2. Remove the three screws inside the upper housing (Just under the lid where the hinge is).3. Remove the screw under the left and right side in back below the vents.4. In the back pull the white ribbon closest to you out of the block, do not try to remove the block itself.5. Place a screwdriver into the slot both on the right and lift of the bottom corners on the back to release the hooks that hold the upper unit.6. Lastly, put a screwdriver into the notches on the bottom of the printer located in the front right and left, they are spring loaded.7. Remove cover.8. The head lock release screw is in the right side of the printer and is partially covered by the lower housing. I drilled a half inch hole into the side as to be able to insert a screwdriver. Turn the screw to the left and the head will rise out of the locked position. You only need to turn enough to release the head.9. Clean the sponges and any areas you see with excess ink.10. Place the cover on the unit enough to plug the white ribbon back in and turn the unit on.If the printer lights stop flashing then you are all set.
