Nick Dow's blog : HP Inkjet Printer Repair
The main reason for repairing HP inkjet printers and HP wide-format printers (plotters) are various breakdowns of the printhead drive mechanism. For example, in Hewlett Packard DeskJet 3820 printers and other HP printers of this series, the most common failure is the parking unit drive mechanism. Externally, the malfunction looks like a crack when trying to print, and the print head does not move.
According by manuals this and other malfunctions are most often caused by contamination of gears, couplings, guides that arose due to the lack of preventive maintenance and the use of counterfeit or refilled cartridges. The fact is that special cleaning units are provided in the design of HP inkjet printers and plotters to clean the print heads. If they are not replaced in a timely manner, excess ink and dust begins to "drag" along the mechanism, causing dirt on prints and accelerating wear and premature repair of the HP inkjet printer. Our engineer can determine the need to replace the cleaning elements during preventive maintenance.
How often should prophylaxis be done?
Each model has its own filter life. For example, in HP DeskJet 8xx and 9xx series printers, our specialists recommend performing maintenance after using 3-4 sets of original cartridges.
When using compatible, refilled or counterfeit cartridges, to increase the service life and reduce the need for repair of the inkjet printer, preventive maintenance should be performed more often, since in such cartridges the ink consumption is usually higher and the filling of the cleaning element occurs faster.
The main signs of the need for preventive maintenance:
The printer gets dirty when printing.
Extraneous noise when gripping paper.
Poor paper grip.
Ink leaking from printer.
We usually repair inkjet printers in our service centers, since high-quality work requires special equipment. You can bring your printer to our service centers or use the delivery service of our company.
There is no need to take the printer anywhere; maintenance is carried out at the installation site.
In order to reduce the difficulties associated with the transportation of large HP printers and plotters, preventive maintenance of wide-format printers (plotters) is often performed by our specialists at the place of installation of the machine. The most profitable solution to ensure the high-quality operation of your plotter is to perform scheduled preventive maintenance work under a contract. Your benefit is not only saving on the cost of paying for the work of an engineer, consumables and spare parts, but also reducing time losses and a higher-quality appearance of your printed documents.
HP Diagnostics
- In order according by hp manuals to see with my own eyes how a malfunction of an HP printer manifests itself, I examine it.
- To perform diagnostics of HP LaserJet printers and color laser printers HP Laser Jet Color have many special modes and settings. I print out a status page, which shows the necessary information: a list of errors, in which units paper jams and other failures most often occurred, the firmware version and much more.
Here are the most typical error codes and malfunctions of HP printers and their decoding.
13.x - paper jams, where x is the code that indicates the location of the jam: 1 - paper feed, 2 - registration unit, 3 - thermal unit, 4 - exit unit, etc.
2N.x - various printer memory errors.
41.x - usually paper size errors.
50.x - thermal unit error.
51.x and 52.x laser and scanner unit errors.
57.x - fan unit errors.
59.x - motor errors.
79.x - formatter board errors.
HP Laser Printer Repair
- Based on the initial diagnostics of the HP printer, I disassemble it, replace or repair the faulty unit, and also service the internal units of the HP printer.
- Next, I check the functionality of the repaired device: I test the functionality of the interfaces, perform test prints in different modes and from different programs, print the service page again and check that everything is normal.
- I wash the case so that your HP printer, when it returns to you, shines like a limousine.
- I finally assemble the printer, perform a printer test once again, and glue a neat sticker with our logo – a “button”, reminding you of the telephone numbers of our service for Hewlett Packard equipment.
- I am writing a report on the work performed on the service and repair of an HP laser printer, listing the replaced parts in detail. I recommend replacements that will be required in the future.
- Together with you we enjoy the result.
