HP LaserJet M1522nf故障-液晶屏显示“Reay 2 download”
Hello!
I know how to solve this problem.
First you must turn your M1522xx on and if it shows "Firmware Corrupt Ready 2 Download",
that's what we need.
If LCD screen is blank, then clear all tasks for this printer and delete its driver from "Printers and
Faxes". Now turn it off and on again. Do it untill "Firmware Corrupt Ready 2 Download" shows.
------------------------------------------
When we see "Firmware Corrupt Ready 2 Download" we should do as follows:
1) TURN PRINTER'S POWER OFF
(USB should stay connected)
2) Delete installed driver (if exists)
3) Manually install driver for M1522xx
(When choosing port, use one of "Virtual Printer Ports for USB" which is your printer connected
to)
4) Run firmware update program from HP Support web page (PRINTER IS OFF)
(ex.:LJM1522_FW_)
5) In firmware update program's window choose your printer (manually installed) and press
"Send Firmware" button
6) Wait for firmware to be completely sent to your printer's task window
7) TURN YOUR PRINTER ON
8) First you will see "Firmware Corrupt Ready 2 Download" message. If there is no such message,
turn off and on again untill it shows. Then message will change to "", ""
and ""
9) When all this operations end, printer'll ask you to turn it off and on.
That's all. No need to contact HP Support or buy any parts.
P.S. While "", "" or "", printer may hang. It's not fatal. Just
repeat all operations again.
To prevent hangs use quality USB cable when updating firmware.
