In its latest “how-to” article, Zhono tackles the sticking of cartridges in Xerox printers.
Most Xerox printers connect to the cartridge chip through the contacts in the printer. The cartridge chip groove (Figure 1) may be stuck in the printer if the cartridge chip is not inserted. Forcibly pulling the cartridge out may damage parts, such as twist or fracture, as shown in Figure 2. 
To avoid the above, Zhono talks in its latest “how-to” article about options to remove the sticking cartridge without damaging the cartridge or printer. Zhono recommends the following:
Figure 3
Step 1: Find a piece of film or plastic (Figure 3) that is thinner than a credit card and slightly wider than the chip.
Step 2: Insert and push the film or plastic to the connecting point (Figure 4) between the contacts in the printer and the cartridge chip groove, and then remove the cartridge.

The contacts in the printer may deform after being used for a long time. So the company adds that some compatible chips for use with Xerox machines have been developed and manufactured by Zhono with lengthened contacts (Figure 5) to ensure communication between the printer and the cartridge chip works well.
