Check if the Pico fuse is blown ? next to the heat sink on the transisitor array with the number 2025.if the fuse is gone than the fuse plus the 2025 transistor must be replaced.

Printer Throws Alarm, HSD, Prop error and Head Problems


Most likely, you need to lubricate the shaft the head moves on and clean the positioning tape (carefully, the marks on it can be dissolved).
Unplug the printer while it's moving the head, so you can manually move the head around. Use light oil, such as used in sewing machines.

Printer prints one line, then alarm light comes on and stops printing.


Sir the printer is giving line because the cartiage or toner is not of good quality so it does not melt properly and produces line while the alarm comes and stop printing is due to the problem in charging cathode or gutter

Alarm flashing goes to prop


This is a "spacing alarm". check that the printhead moves freely from left to right. If not, remove the ribbon and try it again. If it is moving freely then it should be ok, if not it will need most likely the space motor or the main board replaced. In some cases it is also possibly the white carriage cable that runs from your main board to the space motor. Hope this helps.

Remove the ribbon it may be jammed and if this does not work your printer has a problem with either main logic board or carriage motor.
