I have major problems with my LJ Pro MFP 470dw. We got it in March and it worked perfectly. In mid-August, I received the event code 10.01.11. The original (German) error message says 'Die angegebenen Verbrauchsmaterialien kommunizieren nicht korrekt mit dem Drucker.', which means that the toner cartridge does not communite correctly with the printer. In my case, it's always been cyan. As I thought toner might be low, we got a complete new set of toner cartridges (extended version for more than 6.000 pages for ca. 700 Euros...). Exchanging the original cartridge with the new one seemed to solve the problem. I was able to print for a couple of weeks, however, the same error code came up again. I called HP, they replaced the printer and put in my "old" cartridges. Things worked for about 4 weeks (having printed approx. 150 pages), then the event code 10.01.11 popped up again (again after ca. 200 pages printed). Same procedure: I called up HP, they replaced the printer, put in my old cartridges (they even gave me new ones, however these arrived late). Again, a couple of weeks later, the same error code came up. I put in the replacement cartridges that had arrived late: everything worked for another couple of weeks, but then event code 10.01.11 was there once more. I called up HP, they wouldn't replace the whole printer again, but exchanged the controller. We put in a completely new set of toner cartridges, and everything worked - until today...
Taking it all together: with 3 printers of the same model and an even larger number of (at least cyan) toner cartridges, the problem persists. It's always the cyan toner cartridge that seems to be affected, none of the other. We cannot use the printer reliably. HP has given support, but we had to wait for several weeks without having a printer (badly needed due to home office). I cannot believe the problem is with us only. I read one more post regarding the same issue. Has anyone experienced similar problems? Does anyone have a solution?
Thanks for the information! If there is a general problem with the printer model, HP never communicated that to me. I'd be more than willing to bridge the time until there's a permanent fix. However, I'm in need of a working printer (home office) and would need a replacement within a short period of time if and when the event code occurs. I'm not a "power user", but rather print a moderate number of pages (a couple hundred pages a month) which, however, I do need at the right time. Do you have any informaton on the underlying cause of the issue and when and how a permanent solution will be available?
