Question about HP DeskJet 930c InkJet Printer
Printer feeds in a page and starts to print. Then the power and resume lights start to flash. Press the resume buttom and the paper ejects with only the top few lines printed. Tried on different computers - same result. Checked the printer and cannot see any mechanical problems. Ink cartridges are okay. Inside of printer is clean. Paper does not appear to be jamming - it ejects without problems. I've been to the HP web site and checked all the things they suggest but I can't find this particular problem described. Thanks in advance.
Check the print driver in control panel...... if the correct driver for the printer is not installed, or corrupted, it can send invalid instructions to the printer, but let me check....... ahah! found it..... it's a carriage stall (not the horse kind :-') ) but the print head carriage is jamming for some reason, either there is some grit on the carriage bar, or a missing tooth in the drive belt, or the timing strip is dirty..... the easiest to fix yourself would be to clean the timing strip. the timing strip is a clear plastic tape usually behind or below the carriage bar. it looks like it has a grey horizontal stripe across it (actually it is many tiny vertical black stripes that provide the printer with motion and dot timing information). carefully with a window cleaner soaked paper towel, and without too much pressure (that would unhook one of the ends of the strip)wipe the strip clean on both front and back. also if the printer happens to be in an unlocked condition (you can do this by removing power during the head positioning cycle), try moving the printhead at a moderate speed back and forth along the carriage bar and see if there's anywhere where it binds up or you feel more than normal resistance, the printer needs repair, but at least you can tell the technician where to start looking....

Tips for a great answer:
If the printer has been printing continuously for a long time, the Print Head may overheat. To protect the Print Head, the printer may stop printing at a line break for a period of time and then resume printing.
Additionally, if the printer has been printing graphics or photos with intense colors continuously over a period of time, the printer may stop printing to protect the Print Head. In this case, printing will not resume automatically. Turn the printer off for at least 15 minutes.
When the POWER lamp is flashing green, the printer or the computer is processing data. Printing large data such as photos or graphics takes time for the printer and the computer to process, during which the printer may appear to have stopped operating.
In addition, when printing data that uses a large amount of ink continuously on plain paper, the printer may pause temporarily. In either case, wait until the process is complete.
If you are printing a document with a large printing area or printing multiple copies of a document, printing may pause to allow the ink to dry.
