Hello
Check its AC input connection for any loose contact. Check it with pluging it on an other plug point in your home. It is a type of interference, and some electronic and electrical equipments in your home may also cause this trouble when it works. Check these please. OK.

If this is a laser printer, it sounds like you have either a defective drum or transfer belt. Drum would be my first guess.

If the stripe is a thin line, the scanner glass is dirty, if it is wide stripe you have a bad scanner block. EXPENSIVE

Hello sir; Is the stripes allway in same place and you use document feeder to copy, then you have to clean up a piece stripe glass on the plateform, otherwise ,you have to change drum cleaning blade or drum cartridge.

Ink cartridge has dried out.

TRY TO CLEAN AND CHECK MAIN CHARGER AND TRANSFER CORONA FOR VOLTAGE LEAKAGE,AND CHECK DEVELOPER GEAR AND DEVELOPER DRIVE GEAR

Check this link.

1st. Print a report. If the blank stripes are still there, you must remove the drum and t6oner combination and clean the laser glass located on the bottom of the machine.
If the blank stripes do not appear, then the fault is on the scanner of the sending fax machine.
