Dark Shadow Background on Printed Pages

Recently I did a service call for a third-party company to replace an HVPS (high voltage power supply) in an HP M3035 printer for one of their customers. When I arrived onsite and printed a config page the background was so dark it was difficult to read the print on the paper. After talking to the customer, I found out that several technicians had been out there and had replaced various parts. Knowing the third-party company I went ahead and replaced the HVPS per my instructions.

After replacing the HVPS I turned the machine back on and printed a few pages. While the print looked better it was light. I checked the settings to make sure the density was set correctly and econo-mode was turned off. I turned the machine off and back on thinking that maybe a power off then on would fix the problem. To my unwanted surprise the dark background was back. Continue reading

30.1.19 Scanner Lamp Error

A new customer called to have me take a look at an HP LaserJet M5025/39 printer that was donated to their not-for-profit company. The machine had been sitting for several years and when they turned it on they found that the copier function would not work. After debating long and hard they decided to spend a little money and have it looked at to see if it could be salvaged.

I arrived on site to take a look at the machine. When it finally warmed up I attempted to make a copy and got nothing back but a black copy. When I opened the lid to make a copy it was apparent the lamp was not working. I printed a config page and error log report to check the firmware and past errors recorded. Sure enough, it was reporting a 30.1.19 Scanner Error. I ran the scanner lamp test Continue reading

Quality, Reliability and Consistency in Print: Understanding the True Cost of Non-Genuine Supplies

As a service company, your customers look to you for best practices when it comes to getting the most out of their printer investment.  As you know, toner is very important to the developing, transfer and fixing parts of the printing process. The quality of the toner going in is directly related to the print quality coming out and the total overall print costs. 

To provide an answer to the often asked questions about remanufactured/refilled and compatible toner cartridges … Are they safe for my printer? Why do they cost so much less?  Will they print just as many pages? Can they void the manufacturer’s warranty? … it’s important to first understand a bit about the different types of toner cartridges available.

Read more to get a complete understanding of the differences in the various types of toner available (genuine, remanufactured/refilled, and compatible), the effect of each on print quality, overall short- and long-term costs to your service business and to your customer, and the environmental impact of each type of toner (you may be surprised by the facts!).

Printer Cartridge Empty Error

In this last year I haven’t been able to get away from servicing the HP Color LaserJet 5500 and each call I get seems to present an even odder situation than the last one. In this article we’ll explore the Empty Cartridge Error,  how it presented and what ended up solving the problem.

The Reported Problem
The customer explained to me that, one day as they were printing, the machine reported that the three color cartridges (cyan, magenta, yellow) were empty. The customer ordered OEM replacement cartridges but once these new cartridges were installed the error did not go away — the black cartridge still said it was half full but the color cartridges said empty.

When I arrived onsite I first tried reseating the cartridges and cleaning out the cartridge contacts. Second, I disabled the cartridges in the diagnostic menu and printed several test pages. The machine hadn’t reported any errors related to the cartridges and the firmware was up-to-date. Continue reading

49.38.07 Error on Start-up – HP LaserJet M601 and M602 series

Last Week I was called out to work on a M601 series printer that had a 49.38.07 Error displayed on the machine. At first I thought this would be an easy fix; I’d go out, remove the network cable, turn the machine off and back on and the problem would go away. Once I plugged the cable back in the error would return and I could report back to the customer that a print job was causing the problem. This customer has several public computers and printers so I receive more of these types of calls because of the wide variety of information being printed to the equipment.

Anyway, once I got onsite, nothing I did made the error go away. Every time the printer got to the initializing process, even without the network cable installed, the error returned.

After trying all of my known troubleshooting steps without success, my next option was to try a firmware update. I returned the following day, followed the below listed steps to perform an update and everything seemed to work the way it should. However, once the procedure was done and the machine rebooted the error returned. At this point it was either (a) replace the hard drive or (b) wipe the hard drive and start from scratch!

What ended up solving my problem on this machine was to reboot the machine (following the below listed instructions), Continue reading
