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

Machine stopped - alarm light flashing


just saw this yesterday. remove the top rear paper guide. on the left side between the tractor feed and the input slot for the paper, there is a sensor flag that pivots. check for paper scrap caught under the flag. it prevents the flag movement, causes a paper out alarm.

I have an Oki C3400 that wont print


Could very well be the sensor window. I suggest looking at the side of the drum on the right side and pushing a q tip into the opening. heres an older model thats sort of similar instructions. http://www.c3400.co.uk/index.asp?menumode=0&content=sensorerror
Also you can check the exact error code here. http://www.okic3400.co.uk/library/downloads/utilities/c3300c3400smv1115.exe

When the alarm light is blinking what other lights are on. This is the fatal error code with the printer.

Remove the ribbon. if still not moving smoothly unit needs service. 3 year warranty on this unit brand new.
If you cannot move the carriage back and fourth accross,

there is a seriuois issue. unit requires service.
