So your printer just broke down, and you’re tired of having it repaired. Or maybe it’s old, and you know it’s time for a new one.
You can buy a cheap one that just gets you by, or you can get the deluxe powerhouse version that prints 20-50 pages per minute. How do you know which one you really need?
Here are some tips for making that decision
I’ve been out on service calls and have seen, or heard, unusual things happening in the exit area of the HP 4200/4300 printers. What I’ve noticed is that sometimes the paper feeds through normally but with a little extra clicking or snapping noise. Other times the noise is accompanied by the paper not feeding through properly.
There are two exit flags that paper has to go through as it exits out of the machine to the face-down delivery area. One right-side flag is for the face-down bin-full sensor and the left side flag is just to provide equal pressure on the paper to the right side flag. On the bottom of the top cover HP has put two dampener pads like what you see on a solenoid. Over time these pads wear out. Continue reading
Two questions I’ve been asked recently are how to make the machine quieter and how to reduce the amount of paper curl on the sides of the paper.
Paper speeds have gotten pretty impressive on all printer makes and models. Even small printers have awesome print speeds. However, most people have noticed that their personal machines, the ones that sit next to them in their office, are too noisy, especially when they are printing while talking on the phone.
Another issue they’ve noticed is that paper is curling in the exit tray and, after 15 to 20 sheets are in the tray, the paper coming out starts Continue reading
Lexmark recently announced the addition of four new A3/ledger-capable devices to its portfolio of smart MFPs and printers. Discover more about these devices and what sets them apart.
The 13.A2.D2 error means that the paper is failing to get to the pre-feed sensor (PS102). Several things can cause this error. Here are a few troubleshooting tips to help isolate the problem and get it fixed with as little cost as possible.
Is the paper stop arrow lined up?
Remove the paper and paper tray. Verify the paper stop arrow is lined up with the mark on the bottom of the paper tray. If the paper stop is moved too far forward the paper will bind when the tray raises. Also, make sure the paper is properly loaded. Sometimes a few pieces of paper will bend up in the front of the tray causing the tray to not properly lift and feed paper.
Is the access door missing?
In the front of the tray there is an access door for the pick-up roller. Verify the access door is there. I’ve seen situations where these somehow get removed, causing intermittent paper jamming. Continue reading
This topic was covered briefly in a previous post. At that time I didn’t have a defined solution, but since then I’ve gotten feedback from others and I’ve personally fixed a few machines with this problem so today we’re going to get to the solution.
I’ve seen slow printing from the first 500 sheet tray in these HP P3015 printers. By that, I mean, occasionally the paper feeds up into the two feed rollers behind the MP tray and stalls out. This causes the pickup roller to rotate again, pushing the paper up into the registration assembly. In most cases, this doesn’t cause a paper jam; however, if you’re printing a 50 page document you will notice a slight hesitation with every few pages so the output is not at a consistent pace. Also, because the paper is slipping on the two feed rollers, you see two black lines in the middle of the back side of the page about 2 or 3 inches down.
Last week I worked on a printer that was actually having some paper jam issues as a result of this. The machine had 320,000 prints on it and had been operating for a few years with the hesitation and marks on the page without any serious problems related to it. However, with the paper jam errors starting to happen I decided it was time to address this problem. Continue reading
The other day I had a customer bring in an HP M551 printer that was not printing Magenta on half the page. Going left to right the color started to fade in the middle of the page so the right side of the page was completely void of Magenta. The service manual doesn’t seem to tackle this issue so I thought I would write about it.
First, print the Print Quality (PQ) test pages to get a clear idea of how all the toner cartridges are working.
Then disable thecartridge check option and swap the problem toner cartridge with another cartridge. For example, put the Magenta toner cartridge in the Cyan slot and the Cyan in the Magenta slot and the Print Quality test again. This will tell you if the problem follows the cartridge or stays with the slot. If it follows the cartridge Continue reading
