Question about HP OfficeJet 7130 All-In-One Printer
My 7130 has started to occassionaly make a gears grinding sort of noise when attempting to print. It does this when the print/ink cradle is in the far right position (also the noise is coming from that side of the printer). When this happens the printing never takes place. The message in the display states it is printing page 1 but it will hang there forever. I can either just cycle the printer off and on to clear the problem sometimes. Other times it seems I need to unplug and replug it to get it free up.
Filka, You are most likely beginning to experience issues with service station function usually created by the buildup of ink which becomes gelled and gooey, resulting in sticking parts. Two primary points of trouble can be involved; one very easy to see and reach- the other requires a fair amount of disassembly but once inside the job is not hard.
First, right on the edge of the service station (the black box beneath the carriage when it's parked on the right) you will see a narrow white wedge-shaped piece. This is a retracting "wiper" which is supposed to slide forward when the carriage is parked, and to the back when the carriage is preparing to move. It has a small rubber tab at the front edge which wipes ink from a gold contact surface right in front of the wiper. I've yet to see one truly do well at keeping the surface free of ink, but it does keep it from building up. It is quite easy for this wiper to become "glued in place" by all of this ink. Start by raising the maintenance door, causing the carriage to move out to the center and the wiper to retract(if they will). You can then use a dampened paper towel or cotton swabs to clean the contact in front of the wiper, then gently pull forward on the top of the wiper to slide it forward over the cleaned surface. This will remove some of the ink on the rubber tab and begin letting you clean the wiper itself.
The second area of trouble is the service station itself. The sleds and tray are likely to be heavily coated and the only real way to clear them is to disassemble the case for access. You can use the following link to go to a step-by-step photo/instruction guide that will show you exactly what's involved-
