Where to get the pin code wps hp. World of pc peripherals Assigning service menu items

The service modes of Hewlett Packard LaserJet printers allow service engineers to access parts of the non-volatile memory of the device, such as a serial number, a page counter, a maintenance counter, etc. Recently, hp has launched printers with a new entry into service modes, and this approach requires knowledge of a PIN code unique to each printer model.

The service menu opens the entrance:

• setting serial number   a printer;
• clearing the event list (printer error list);
• full NVRAM initialization;
• setting the control panel message language;
• obtaining various information, etc.

In earlier models of printers, in order to enter service modes, it was necessary to turn off the printer and after a certain period of time turn it on again while holding down the corresponding keys on the control panel (usually the [Cancel] and [Select] buttons)

Assigning service menu items

• Clear event log

  This menu item allows you to clear the printer event list. The event list stores error codes and other events that occur in the printer. In addition, for each of these events, the state of the page counter at the time of this error is indicated. The event list allows you to evaluate the statistics of printer failures and get information about those nodes and printer modules that require attention from a service technician. Execution of this menu item completely clears the event list, as a result of which the failure statistics become inaccessible.

  Check your computer Make sure that the computer you are using is connected to the network. Check your web browser Make sure that your web browser meets the minimum system requirements. Embedded Web Server Specifications. If your web browser uses proxy settings to connect to the Internet, disable these settings. Documentation for your web browser. Click "Setup" and "Network", and then "Network Printing Options." On this site you will find information and utilities that will help you solve many common problems.

  Not every computer in a household needs its own printer: it can be easily integrated into a network. Many computers: this not only saves the initial investment, but also takes up space and, finally, electricity. Because even multimedia printers usually do not use their device around the clock.

• Total Page Count

  This menu item stores the current status of the total counter of printed pages. When you enter this menu item, you can edit the value of this counter, setting it to any value. Installing the page count is usually necessary when replacing the formatter board.

• Maintenance Count

  This menu item stores the count of pages printed since the last scheduled maintenance. This counter allows you to get information about when the next routine maintenance is required, and also allows you to plan the cost of purchasing a repair kit. When you enter this menu item, you can set this counter to any value. Installing the page count is usually necessary when replacing the formatter board.

  But how can you do this? The vast majority of modern routers support the standard. The procedure is very simple. From here it is automatically recognized by all computers. . Most modern routers have this feature and allow you to use the printer on the network in this way. How is it with your router, you should look in the manual? It can simply work by connecting the printer to the router. Therefore, it is better to connect the printer as a network printer.

  Network printers on the router are just printers.

  This may be desirable, for example, if you rarely or directly use the scan and fax feature on your multifunction device. However, in such cases it is much easier to resort to the third option. For this you need a computer that is turned on as much as possible.

• Maintenance interval

  This menu item indicates the interval for issuing a message about the need for service. It is through this number of printed pages on the display of the printer that a warning about the need for service is issued. The service technician can set any interval for issuing this message by editing the counter value. At the factory, this counter is set to the standard value for the corresponding printer model.

  Confirming network settings

  Of course, to share a printer with a network, you must first install and enable it. Download drivers appropriate for your printer. In the device user manual. . Lasers get home. This monochromatic model includes what we used to have in inkjet printing: it is multifunctional and wireless. But those days are over, today we can find many models laser printersdesigned specifically for home and even laser multifunction devices.

• Serial Number

  In this menu item you can edit the serial number of the printer stored in the non-volatile memory of the printer. The value of this number must match the serial number printed on the body of the printer. Reinstallation of the serial number should be done when replacing the formatter board.

• Cold reset paper

  This menu item specifies the default paper size that the printer will return to after the Cold Reset procedure - Cold Reset. There are only two of these default formats in HP printers: A4 and Letter. Of course, in our conditions, in this menu item you need to select the value A4.

  As a home team, its design takes on a certain meaning. When we do not use it, it comes down to a small black box with a great style, largely due to the excellent quality of the materials. When using it, obviously, it will take something more, because we have to expand the feed tray and exit. Perhaps the only thing we could criticize in this aspect is the scanner lid, which is slightly weakened, but this is due to the fact that it allows you to increase its height if the original document you want to scan is too thick.

• Service ID

  This menu item is not found in all printers. In printers, more early models can not meet such an item as the Service ID. This section began to include in service menu recently. This item should contain information about the date of putting the printer into operation (or about the date for replacing the formatter board). Information about the date of putting the printer into operation can be very useful for determining the period of validity of the printer warranty. HP printers are not equipped with their own internal clock, so if the printer is not connected to a date source (driver or embedded web server), then the customer service cannot clearly speak about the possibility of providing warranty repairs. In this case, the date of putting the printer into operation and the period of time during which the printer is actually operated cannot be determined, since the value (00000) is indicated on the display (as well as in the configuration sheet). When you enter this service menu item, you can set the Service ID value. Here, however, it should be noted that HP has developed a rather complex date format displayed in the Service ID. In the five-digit numeric code Service ID, the year, month and date are encrypted, and a rather peculiar algorithm is used to encrypt this number.

  In the upper part we will find several buttons with which the team counts. Among them, there is a button to activate environmental impressions, which will allow us to save on toner and extend the life of our cartridge. Therefore, trying to print or scan a photo, we may notice some flaws in the final document.

  However, we may have noticed that copies are usually much darker than the original document, without the possibility of clarifying them. Because of this, copies are often somewhat saturated, but if the document is a text, this effect is almost invisible. This allows us to easily copy front and back documents to print them on one page.

In multifunctional devices (with mfp letters) that perform, in addition to printing, scanning and copying functions, the service menu includes the ability to set a copy counter, scanned document counter, automatic document feeder counter, service counters for individual device modules (scanner, ADF and etc.).

For color laser printers, the service menu also includes additional items such as consumables counters: fuse meter count (Fuser Kit Count) and transfer meter count (Transfer Kit Count).

Service Modes laserjet printers   from Hewlett Packard allow service technicians to access non-volatile memory elements such as a serial number, page counter, routine maintenance counter, etc. After some time, HP began introducing a new approach to entering service modes in its printers, and this approach requires knowledge of a PIN code unique to each printer model.

The service modes of the Hewlett Packard laser printers of the Laser Jet family allow you to set the page counter value, at which a message will appear on the control panel indicating that maintenance is required. However, installing a page counter may be necessary in other cases, for example, when installing a new formatter board (data processing board from a PC, which has interfaces for connecting the printer to a PC). The fact is that the value of the page counter is stored in non-volatile printer memory (NVRAM). This memory is a microcircuit electrically - a reprogrammable ROM, denoted in the literature even as EEPROM, EEPROM, Flash-memory. This memory is physically located on the formatter board. Therefore, if a formatter board is being replaced, it is necessary to install a page counter by writing the value stored in it on the “old” board. Otherwise, when installing a new formatter board, you will receive a “new” printer that has not printed a single page yet, i.e. whose page count is zero. Naturally, such a page count will not reflect the actual wear of the printer and its individual mechanisms.

In addition to the printed page counter, the user's printer settings (resolution, paper size, fuser temperature, font settings, and more) are saved in the NVRAM of the printer. Sometimes it is necessary to reset all the set values ​​and return to the factory settings. Such a reset to the factory settings can also be accomplished using the printer service modes.

In service modes, other options appear, such as:

- setting the serial number of the printer;

- clearing the event list (printer error list);

- full initialization of NVRAM;

- setting the control panel message language;

- obtaining various information, etc.

In earlier models of printers, to enter service modes and to perform other functions, it was necessary to turn off the printer and after a certain period of time turn it on again, while holding down the corresponding keys on the control panel (usually the [Cancel] and [Select] buttons) .

But in modern models of printers decided to use another option, in which it is assumed that in the user menu of the printer initially there is an item called Service Mode. However, it is impossible to simply get to the Service section through the user menu. When you try to enter this section of the menu, the printer asks for a password (PIN). When you enter the correct PIN, access to the service menu is allowed, and its items become available. The complexity of this method lies in the fact that for each printer model there is a unique PIN-code, which, of course, does not fit other models.

In order for a service technician to work professionally with all modern models of Hewlett Packard printers, we present a summary table (Table 1) of passwords for entering their service modes. This pivot table   allow engineers to have the necessary information at hand, rather than look for it in the service manuals and other sources of information.

Table 1. PIN codes for entering the HP LaserJet printer service mode

What is the service menu? And what opportunities does a service engineer have when working with him? Let's see.

Among the required items of the service menu, we find:

1. Clear Event Log (Clear Event Log)

2. Setting the total page count (Total Page Count)

3. Installing the maintenance counter

4. Setting the Maintenance Interval

5. Setting the serial number (Serial Number)

6. Paper Size for Cold Reset Paper

7. Setting the Service ID
