Try rebooting the machine 70@;then flush the print head. If it still doesn't print you will have to replace the head. There are some online companies that can guarantee to flush it.
Streaks can come from several sources. Since you said they appear near the end of a plot, the print heads may be running out of ink before the end of the job. This would happen if you had air in the ink tube system and consequently in the heads. When the printer is idle for a while, ink will migrate to the bottom of the print head so when you print again it is ok for the first part of the plot and then gets to the air bubble.
Open the back door of the plotter and look for air bubbles in the ink supply lines. If air is present, it needs to come out. There is a purging tool at Designjet Ink Tube Priming Tool . The print heads may need to be replaced, but not before the tube system is clean.
The calculator thinks you're trying to graph a function that involves stat plot features when the function actually does not. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.
Hey. I had the exact same problem as you and all I could do was reset the settings to the default settings on the calculator. All you have to do is turn the calculator on, his 2nd (it should say mem right above it). Then click reset then RAM.
You need to lubricate the shaft that the carrage runs on. If you dont have the correct lubricant, use sewing machine oil. Switch the machine off and using a cleaning fluid such as methelated spirits or benzine, carefully clean the shaft. Take care not to damage the encoder strip (plastic strip running just above the shaft, its also sharp, dont cut yourself) Also clean the outside of the bushes on either side of the head unit. Then with your hand move the head unit to the middle of the machine and put ONE drop of oil on either side of the head making sure you dont mess any and also making sure it goes to the back and front of the shaft. Move the head slowly left and right, spreading the oil outwards. If necessary use a second drop but do not over oil the shaft under any circumstances, the more oil the more dust builds up. This will solve your problem.
This is a common problem on the 500 range, not so common on the 1050. A quick way around the problem (using the parallel port only) is to load the HP Designjet 750c drivers. Send the drawing to the 750 using memory in computer option and it WILL print.
Was the plot originally done on a size D or E plotter.. A .pdf is generally not a good way to send a plot that has to be done to scale.. Can they re-send the plot in a hpgl format, or a format that you can use in another program, liks ACAD, and then print it through that program? This would provide you with some control, that a pdf document will not allow.
This is just a stab in the dark for me, but I am familiar with plotters in general, just not the many formats to print from..
