Laserjet 4+ errors 14 & 13


I have an HP Laserjet 4+ printer. A few weeks ago it started displaying error message "16 Toner low" I assumed the toner was indeed low and ordered a new cartridge (and it may well have been). However, before I started noticing any change in the quality of print, I got a new error message: 14 No toner cartridge. This perplexed me as I had a toner cartridge in the printer. The new cartridge came (remanufactured) and I put the new toner cartridge in and got the same error. At first I thought, perhaps I got a bad cartridge, but I tried a friend's cartridge known to work and had the same problem. I've examined the metal pins that the U-shaped bracket on the cartridge goes into and they appear ok. I've also cleaned the larger pins which I presume are the high-voltage contacts. Still no luck. I tried playing with taking the cartridge in and out and turning the printer on and off (with pauses, not quickly) for a while and was able to get it to recognize the cartridge. But then I got an "13 Paper jam". I've checked all paper passages and everything is clear. The printer didn't even start to grab a page, and I got the same error whether I used the regular try or the manual bypass. Does anyone have any ideas on what could be wrong?
