Encoder sensor for DesignJet printers

This YINGHUA encoder sensor is a printhead component built for HP DesignJet large-format printers. It fits models including the Z2100, T1200, T2300, T1120 and T1120PS series. Service technicians and print shops use it to restore accurate carriage positioning after the original sensor fails. The part replaces OEM numbers such as Q6683-67004 and Q5669-20570.

Thermals noise and power in normal use

As a passive optical sensor the unit generates no measurable heat and operates silently. It draws negligible power from the printer’s carriage supply and requires no active cooling. The component simply tracks the encoder strip to maintain print alignment during every job. Buyers needing a complete printhead assembly or a different sensor format should look elsewhere.

Questions about this item

How do I install the encoder sensor on a DesignJet T1120 PS and which step is often missed?

Power off the printer, remove the carriage cover, disconnect the old sensor cable, fit the new 44-IN 24-IN encoder sensor into the carriage slot, reconnect the cable, and run the carriage calibration from the front panel — skipping calibration causes alignment errors.

What maintenance will the encoder sensor on a DesignJet Z2100 need later?

The sensor is a non-serviceable printhead component; if print quality drifts or the printer reports an encoder fault, replace the entire 44-IN 24-IN encoder sensor — no cleaning or lubrication is required.
