Your question is not detailed. Are you talking about the plotter HP100? There are many kinds of sensor errors!See what kind you are.22:10 Ink supply station error[Detailed]
It may be that the ink cartridge is really empty. Remember to check whether the toner is used up. If it is full, there is still a prompt. It may be a sensor problem and needs to be cleaned or replaced
It may be the ink cartridge. Try replacing it with a new black ink cartridge. Sometimes the old ink cartridge will deteriorate and affect the printing effect
Why does the printer always give a prompt every time I start printing? Why can't it print? I just hear the machine ring for a long time and don't see the paper printed out. Why? This makes me worried and dissatisfied
What kind of thing? I bought 3 sets, and each set always reports an error when it is turned on. It should be a reminder of paper shortage. Put the printing paper in place or report an error. Press Cancel and remove the paper do not work. You must unplug the battery, and then restart the machine. It may take many consecutive times to restart the machine to return to normal. I don't understand.
