Question about Canon imagePROGRAF iPF8400 44in Printer
When this happens, usually in a middle of a print job, I turn off the printer and turn it back on, it will work again for a while, but print speed is much slower than normal. What can I do to get this fixed?
"VHT leak detection error of left printhead,
in case of VHT exceeds rated value or falls
below the rated value."
So, error shows left printhead feeding voltage problem. It can be result of fault:
-Carriage relay board;
Low speed of printing can be when printhead have overrange with it temperature; and when printing, printer makes a pauses to cold printhead. More information you can get from file PRINT INF under SERVICE MODE.
If you are a "ordinary user", looks like you can only try to change left printhead (success not guaranted!).
