Dictation. (Excuse the-typos.)
At this point I am not able to help you. Over the years I have owned several different kinds of printers, all the way from the old dot matrix printers up to laser printers. At the present time the LaserJet printers are the best bargains around in new printers. They offer scan, printing, copy and fax operations all in one unit. And most of them have wireless support. Still, these printers make terrible mistakes sometimes with paper handling and alignment issues. In some cases it is almost impossible to fix the printer even using the recommendations made by the manufacture. They are made to be very, very low cost and is very difficult to fix anything that breaks. As a general rule, replacing the color cartridges also gives you a new print mechanism. So he put in a new color cartridge you should be getting a new print mechanism built into it. However, I don't really know how the things work. I just do what they say in a manual and either it works or doesn't work. In a few cases you might be able to unclog the printheads by using a solvent or by doing something mechanical. Some of the things I have tried a rather crude and primitive and in a few cases worked. But when it comes right down to it, you just have to have a fresh cartridge to put in the printer. If the print is not looking very good you have to figure out some way to block the have printheads and remove excess excess ink from the mechanism. This usually means using some kind of tissue paper or even toilet paper to try to soak up the loose think. I have had to throw away or stop using some inkjet printers because it just got to the end of their life. The expected last time use of a cheap LaserJet printer is maybe two years. In some cases it might be worthwhile to buy an extended warranty if that is possible. Often times the printers to come with a one-year warranty and if something goes wrong you just have to send your printer in and hoped they will send back the same one do you or a printer that will work just as good. I once had a real laser printer that went bad on me but I had a warranty with it and I made good on the warranty and got a new printer. But eventually even the new laser printer fails on me.
Or I should say I failed it. I just could not keep affording those very expensive color cartridges that are used on a color laser. So my budget now is dropped down to using ordinary LaserJet printer that usually sells for less than $200. Once in a while you can find a LaserJet printer on sale $150.
If putting in a brand-new ink cartridge does not resolve the issue, you will have to exercise your warranty options and hope they send you a printer that works good for the rest of the warranty contract.
More information about how to care for LaserJet printers can be found on other websites. Generally on this site we deal with things are just rather simple and to the point unless it has to do with a software issue.
http://www.wikihow.com/Clean-a-Laser-PrinterThe above is only for a laser printer. It does not apply at all to the laser-jet printer. With a Laser jet you have to stick to what the company says and use only the software controlled print-head flush.
Depending on where you live, there might be some technicians in your area that are wizards on fixing up LaserJet printers. It just depends on where you live. The minimum wage laws in many areas make it nearly impossible to find a good technician in any of the major cities. But overseas, you can often find Wizard technicians who received a very low wage and are very willing to fix anything. But not so here in the USA and in many parts of Europe.
