Bin Dump-Canon Pixma MG6840 Chassis Main Board QM7-4414 Firmware-Digital Download No Refund

Found this item on a Reddit post somewhere and their YouTube video on how to replace this module. My Epson ET-3850’s WiFi has been inconsistent the past 6 months or so and then finally clonked out, giving a WiFi error message on the screen. Without the WiFi working I wasn’t able to print anything via AirPrint, only hardwired via USB. For $25 this was worth a shot to bring it back to life. The disassembly and swapping out the module was relatively easy, just follow their video tutorial. It was a simple plug and play. My printer’s WiFi is stable now for over a month! No resets, reboots or reconnections needed! Thanks for this, highly recommended!

Excellent replacement ink. I've been very happy with BCH ink for several years. Previously I've used this set of six in an Epson XP-960 and now in an XP-970. The colors are bright, well saturated, and produce excellent results with any print software.

The HP 9018 Paper Pickup Roller Assembly precisely matches the original assembly that was no longer feeding paper properly. With the help of a flashlight it is possible to to see the new rollers that are spring loaded in contact with the top surface of the paper stack in order to feed it properly into the printer as a document or image is printed. There is still an additional problem with the printer that is greatly slowing the printing process that is so far inexplicable, BUT the new roller assembly does its job correctly. The original roller assembly would only feed paper if there was a very thick stack of paper, but would not drop down as needed to maintain contact with the paper stack in order to feed the paper when the paper stack was reduced to about 3/4 inch in thickness. The new paper roller assembly from BCH is a great solution.
