Printer does not reset


NVRAM initialization/cold reset
NVRAM initializer sets all default variables stored in NVRAM back to factory default values or to a default ROM value, depending on the variable. It also performs a system reset.
NVRAM initializer resets the following:
! all menu settings to factory default values
! factory settings such as formatter number, page counts, factory
paper settings
To perform NVRAM initialization
1 Turn the printer off.
2 Press and hold down the GO button.
3 Turn the printer on and continue to hold the GO button for at least 20 seconds. During this process, the GO button, Attention, and Ready LEDs will each turn on.
4 Release the GO button.
5 The printer LEDs will begin cycling. The NVRAM-unit process will run until the printer is in the ready state.

1. Connect light blue console cable between a computer (serial) and the 3COM switch (RJ45 console port)

2. Open PUTTY or Xshell or HyperTerminal with a serial connection and the following settings (19200, 8, 1, N) If not connected may use 9600 or 115200 bps

14. If you type "summary" you will see all the switch details.

Amongst these details are the IP address of the switch. If you have DHCP on your network this switch is connected to it will receive one as in my case below, so I can now configure the rest via a web browser.

If not you can use the "ipsetup" command to set a static management IP and access via a web browser.

15. Once you can access the web management page for the switch make sure you set a strong password for "admin" and store it in a secure encrypted location for next time.

16. Don't forget to save your new configuration! Otherwise the switch will be at factory defaults if the power goes off!!

CM 1015mfp Colors are not aligned. when printing the characters looks like 3D.


If nothing else works, you may have to manually calibrate the dials inside the mirror box. This video link will show you how. http://youtu.be/R1DIko0a1MA
This may be necessary if the printer got bumped really hard.

How can I perform an NVRAM initialization with my HP CM1015 MFP


NVRAM initialization
CAUTION NVRAM initialization will erase all network settings. Before performing NVRAM
initialization, print a Network Configuration page, which contains network-setting information.
NVRAM initialization performs the following actions:
? Resets all customer-accessible menu settings via control panel and software back to the factory
default settings
? Resets the language to the value set at the factory
? Resets the default media size to cold reset media size
? Resets the symbol set to PC-8
NOTE The following steps reset the same NVRAM locations that are reset using the
Restore Defaults option in the control panel Service menu. The following process should be
used if the MFP does not come to a Ready state and an NVRAM initialization is desired.
Use the following procedure to perform an NVRAM initialization.
1. Turn off the printer.
2. Press and hold the Right arrow and Cancel buttons simultaneously.
3. Turn on the printer.
4. When you see the message Permanent storage init, release the Right arrow and Cancel buttons.
When the NVRAM init is complete, the printer returns to the Ready state.

Whenever I print my document, it doesn't exist the document I want to print but many strange symbols appear on the printed paper, how can I solve this problem?


Cold reset
A cold reset changes most system parameters in NVRAM to the factory defaults. However, unlike NVRAM inititialization, a cold reset does not reset the page count, the paper tray sizes, language, or formatter number.
Note If an HP Jetdirect card is installed, remove it before performing a cold reset. Otherwise, the procedure will also reset all the HP Jetdirect settings as well as the printer settings.
To perform a cold reset
1 Turn the printer off.
2 Press and hold down the GO button.
3 Turn the printer on, and continue to hold the GO button for at least 5 seconds, but not longer than 15 seconds. During this process, the Attention LED will turn on.
4 Release the GO button.
Note If both the Attention and the Ready LEDs turn on before you release the GO button, you must start the procedure again with step 1.
5 The printer's LEDs will begin cycling. The cold-reset process will
run until completion, and the printer will return to the ready state.

If not work, tris this

NVRAM initialization

CAUTION Only perform the following procedure if absolutely necessary.
Performing an NVRAM initialization resets some parameters that cannot be restored later.
NVRAM initialization sets all default variables stored in NVRAM back to factory default values or to a default ROM value, depending on the variable. It also performs a system reset.

NVRAM initialization resets the following:

  • all menu settings to factory default values
  • factory settings such as formatter number, page counts, and factory paper settings
To perform NVRAM initialization
1 Turn the printer off.
2 Press and hold down the GO button.
3 Turn the printer on, and continue to hold the GO button for at least 20 seconds. During this process, the GO button, Attention, and Ready LEDs will each turn on.
4 Release the GO button.
5 The printer LEDs will begin cycling. The NVRAM-unit process will run until the printer is in the ready state.

I have 3Com Baseline Switch 2924-SFP Plus i need to manage it but i forget the administrator password how can i reset this switch to manufacture configuration or how to reset the password


First,"There is usually a small button on routers that can be accessed with the tip of a pen or a paperclip. When you find that tiny button, hold your pen or paperclip down on it for approximately 10 seconds until the router resets itself to factory defaults."
After that, you can contact the manufacturer to get some helps if you still have problem.

BTW,

My problem is i have all yellow ports flashing in 10 3com 3300 switches in the same time. please help me


  1. Using a Null-Modem Cable , hook up the Console port of the switch to an available COM port on a computer (cable must be able to provide serial port communication between 2 computers).
  2. Set up a Hyperterminal session to that COM port (e.g.: com1), with the port settings at 9600/8/N/1/N (. When the screen comes up blank with a blinking cursor, hit [enter] once or twice to bring up a login prompt.
  3. Alternative to 1 and 2 above, if there is a known assigned TCP/IP address for the switch, one can telnet to that address, hit [enter] once or twice to get the login prompt.
  4. Default logins to try are admin/(no password) or security/security. One of those 2 should bring up the management menu.
  5. To reset factory defaults, type SYSTEM[enter] then type INITIALIZE[enter]. This will reset everything that has been set up on the switch, with the exception of the TCP/IP address, if there is one. All other previous configurations will need to be re-entered.
  6. You can type in username "3comcso" and password "RIP000". It will ask you to reinitialize the switch. This will reset all settings including passwords.
