Need help for cleaning epson r300, have a kit
ANSWER : Don’t worry about the paper towel. Keep the heads as far to the right as you can and the fluid will just go into the waste sponge underneath. There’s nothing you can damage with the fluid. I wouldn’t worry about the pad that got torn. Just insert the syringe in the nozzle and gently push the fluid down into the heads. This site sold tens of thousands of those kits and I guess the instructions were pretty good because there was never a single complaint.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.

HP Designjet 750C+
ANSWER : I was replacing the belt on my 750c and let the y-axis motor slip out of my hand. This caused the two wire terminals to disconnect from the motor. Does anyone know which terminals the white and black wires attach to? One of the terminals has a red dot beside it and I assume this is an indicator, but do not know which wire connects there. Any help would be greatly appreciated.

Need help
ANSWER : I usually look for screws that might be holding it. If it doesn’t come off after removing the screws, sometimes you have to slide it to remove it. If that doesn’t work, then you get out the small, flat bladed pocket screwdriver. Use it to gently pry around the edges of the panel. Have you tried grabbing the paper clip with some needle nosed pliers? Either that or a small magnet to pull it out. Another possibility would be to hook the clip and pull it out that way.
