Paper Feeder Assembly And Cassette Paper Pick Roller

Contributed by Haresh Karamchandani

A client recently called and complained that their HP5550dn Multi Function Printer was not functioning well. We visited the site and found that the Printer was giving error message 13:01:00 Paper Jam in tray 1. We went online to check what this error message meant and learnt that the problem could be with the Cassette Paper Pickup Rollers or Paper Feeder Assembly.

We opened up the Printer and discovered that the client had inserted a Cyan Toner Cartridge WITHOUT removing the seal!! This caused the ink in the cartridge to overflow all over the mechanism of the printer. The whole printer was polluted with the Cyan ink and it took us 2 hours to carefully open the printer and blow out the ink and clean wherever possible.

Some ink had entered inside the Paper Feeder Assembly and jammed the gears. We cleaned the gears and sensors and tried to take a printout. The printer worked, but only for one printout! The machine has been brought to our workshop and we have opened up the Paper Feeder Assembly to check what the problem may be. We discovered that due to the ink jamming the gears and sensor the PFA has started to malfunction and cannot be repaired.

We have ordered a new PFA from HP USA along with a complete maintenance kit to replace some Cassette Paper Pickup Rollers that have worn out.

The parts will be shipped via Fedex and should be arriving in about 10 days time. Once we replace them the Printer will be up and running.

What amazes and amuses me is that clients are so na├»ve that they make such errors which end up costing them so much money and trouble. If they would have carefully removed the seal from the Cyan Cartridge this problem would not have risen! Also the client has been using a Fake cartridge which was pointed out to them. They have ordered a set of genuine cartridges which will be installed in the printer before delivery.
