A few days ago I was called out to work on a HP CM4540 that was getting a 49 Service Error. The customer called me and explained that they had already tried to clear the error by turning the machine off then back on but the problem came back. I advised the customer to remove the communication cable and reboot the machine to see if the problem went away. Of course, it did, so I told the customer to delete all print jobs in the print queue and then try to print something simple like a windows test page. The next day I received another call that the problem was back and now would not go away. Continue reading
Historically, businesses have purchased printers and used them until they expire, which can take 10 years or more in some cases (we know some of you still have Optra S devices from 1997 out there!). Yet, these same businesses are leasing other output devices, such as copiers and fax machines, and replacing them every three years. Why is there such a big difference in life-cycle strategy for such similar technologies?
Is it because copiers are thought to be inherently less reliable and require replacement much more frequently? Traditional copiers may have been less reliable, but the migration to digital printing engines brings them into a class that is much closer to printers, simply with added scanning mechanics on top. For example, Lexmark’s multifunction printers (MFPs), which can be used as digital copiers, are built upon the same reliable engines as our award-winning printers. So, the reliability of the mechanics in the MFP is similar to the printers, which may be used for many years. With that in mind, the recommended life span should be similar between MFPs and printers.
Several years ago, Lexmark engaged in a study with a large corporation to determine how often it should replace its printers. [Read the full article here]
In recent months I’ve seen an increase in intermittent paper jams related to these HP 4200, 4240, 4250, 4300 and 4350 LaserJets. Unlike the last ten or so years, replacing the feed rollers isn’t always doing the trick. I’ve been replacing more and more pick up solenoids for the cassette tray pick up assembly.
When the solenoid actuates, the pick up assembly engages and lowers the pick up roller. There is a foam pad on the solenoid that dampens the noise when the solenoid actuates. As the machine ages, the pad wears down and the tape underneath causes the solenoid arm to stick. When this happens, the pick up roller stays down and occasionally picks up multiple pages.
Typically, if you’re only printing one or two pages at a time you won’t have too much trouble. However, if you are printing large volumes, it can be a more serious problem. Continue reading
Enterprises of all kinds depend on all kinds of workflows to execute strategy. Yet much of the inefficiency inside organizations can be traced to their processes and workflows. And even when you realize the problem, you may hesitate to act because it seems too complicated or expensive to fix. That’s the stalemate IDC Group Vice President and General Manager Angele Boyd takes on in this Expert Series video. She suggests you may have a solution already in place.
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!).
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
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
