Yes. Both print and copy jobs rely on the ROS to expose the drum. If the ROS fails, the machine cannot generate any image—whether from a scan or a network print job.
: Without this "handshake" between the sensor and the gears, the printer goes into a defensive lockout to prevent mechanical grinding.
Worn or damaged drive gears within the main drive assembly that prevent the link bar from moving correctly. Xerox Fault Code 043-343
Follow these steps in order to attempt to resolve the issue. Proceed with caution, and always ensure the machine is powered down before performing any internal inspections.
If you have verified the ROS works (by testing it in another identical machine) and the harness is intact, the IOT board is faulty. This is a $300–$800 part and requires firmware reloading. This is strictly a technician-level repair. : Without this "handshake" between the sensor and
The ROS unit connects to the IOT Controller Board via a flat flexible cable or a multi-pin harness. Vibration from daily operation can loosen this connection. Corrosion or a pinched wire will also generate this fault.
The most benign cause is a physical obstruction. This could be a staple, a paperclip, a sticky note, or a thick folded corner of a previous document that snapped off inside the feeder. These debris items can block the deskew gate or jam the rollers. Proceed with caution, and always ensure the machine
To understand code , you must first understand the acronym ROS (Raster Output Scanner). The ROS is the "engine" of the laser printing system. It takes the digital image data from your computer and uses a rotating polygonal mirror and a laser diode to project that image onto the photoconductor drum.
Before diving into the solution, it is helpful to identify the usual suspects. Why did this happen in the middle of your print job?
