News — Designjet 500 800 Technical Help

Hello from New Zealand. Since I have replaced the belt on my printer I have printed in black and white mostly but not much. I tried printing today but after a few sheets it start to hit and miss the ink. It was as if it was spraying ink in some place and not in the others and in the final sheet it virtually didn’t print anything. I did a print test page and it didn’t print in color and was mostly yellow and black. I didn’t get any error message or anything until I ran a align printhead test...

I have an HP Designjet 500ps. I have recently changed the carriage belt using your video but I am getting "Error 87:13 - Possiblty Paper Jam com up" I have followed the instructions on the screen a number of times but can not seem to get past this point. Would you have any suggestions?  The plotter is not able to detect the lines on the encoder strip.  The encoder strip may be installed incorrectly or the trailing cable is not installed correctly.   The first thing to check is to see if there is any deflection in the encoder strip...

Last week I purchased a new belt and installed it. Everything went well had no problems. But now it prints a double line and shadows text. Some areas are printed correctly.

I changed all the inks, print heads, Black (twice). Thanks Ted The problem is the carriage height is wrong.  There are 2 plastic pieces on the rear of the carriage that control carriage height.  One is a spring loaded finger...

From our conversation from today. .. the printer printed 2-3 pages then just cut off 1/4 of the next page. .. do you think it's air in the line?   HP. 500 Thx. RobertIf a color simply faded out, yes, it is air in the ink tube system.  Replace the ink tube system.

Before I purchase the belt kit #C7770-60014-K from your online store… I was wondering if we should be prepared to replace any other items as a “overhaul” on the 7 year old plotter? We don’t print daily.  The machine may be used once a week at best for print one or two black & white AutoCAD 2D line drawings.  No photos or images are printed. Any ideas on the life expectancy of the ink tubes? Ink tubes are usually ok until they leak ink or let air in.  If you are not experiencing either of those problems, the tube system...
