I ordered and replaced the belt in my HP designjet 800 like it is shown in your tutorial. designjet-500-800-carriage-belt-replacement But now I have the message on the screen: "Open and check printhead cover is properly closed" I cannot solve this problem.  Can you please tell me what to do?Philippe The plotter thinks the carriage print head latch is hitting the frame.  It probably isn’t.  Something is causing extra friction or an obstruction in the Y-axis.  With the power off, move the carriage by hand all the way left and right to try to determine if it is hitting something or has...

The error code 17:11 is not an error code listed in the service manual.  It seems to occur at the beginning of initialization and the plotter gets stuck there.  It is useful to use the green light on the power button to troubleshoot the problem rather than to try to interpret the code.If the green light is blinking twice every few seconds, the plotter cannot find the data cable that connects the interconnect board (the board the control panel plugs into) and the electronics module.  Try reseating the cable at the interconnect board and at the electronics module.  If the...

We just received a replacement drive belt for our HP 500 from your company.  Directions and product are great.  Quick question.  Now that the new belt is on the carriage seems to be hitting the black support beam thing just under the top cover.  Almost seems like the ink tubes into the print heads are sticking up to high.  The tube assembly is locked into place as the directions say.  Am I missing something?  Any help would be greatly appreciated. My suggestion would be to get the carriage out into mid machine with the power off.  If it is at...

I have purchase a belt for my 500 and now it's showing a flashing "X" on the display over a drawing of the printer itself.(See photo attached) The printer goes directly to this mode and the on/off button is flashing too. I can't get it into service mode. Can anyone tell me what to do or what I need to purchase to repair this?Thank you. David- The flashing X in the front panel of HP DESIGNJET 500 means that the plotter does not like the installed ink cartridges for some reason.  The ink supply station was unplugged from the interconnect...

We just bought a belt from u guys to replace a 24" 500 plotter. Before the belt arrives a new staff messed around with the plotter and jam a 7 page bond paper, after we removed the jam the plotter just keep on rolling backwards. What could be the problem. No error code is shown, it just spinning backwards all the time. If in case a component giving the problem, do you have a replacement part that we can buy. Thank you so much. The plotter is trying to unload the paper.  There is only one sensor that is looking...
