Top 20 HP LaserJet 4 plus Printer Questions & Answers

Can you ping the i.p. for the printer

For which operating system. Any version of Windows starting with XP should have a native driver for this printer already installed.

Have you tried using the VISTA driver? Many VISTA drivers work with Windows 7. Here is the link... http://h20565.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=57562&lang=en&cc=us

A4 refers to a paper size, so its asking for that size of paper to be loaded.

What this means is that the print job you sent to the printer is formatted for and designated as being ready for printing on A4-sized paper, which is a European size that is 210 millimeters wide by 297 millimeters tall. This is close to what Americans will refer to as letter size as that standard is 8.5 inches by 11 inches while A4 is 8.27 by 11.7. If you have standard letter-size paper loaded into the printer and you want to print on such paper, then you need to go into whatever program you are using to write the document (for example, Microsoft Word, Corel WordPerfect, etc.) and set the option in the Print... dialog window to print on Letter rather than A4. You also need to cancel the print job currently in the printer. This is done by holding the Shift key on the top of the printer and pressing the button that says "Reset" underneath it in purplish-red. This will flush the memory of the printer and make it ready for the next print job. As it's been a few years since I last worked on one of these printers, I cannot remember if you also need to hit the Online button first (so that it is offline, indicated by the light being turned off on said button) before you can reset the printer but if so, then just hit that button, reset the printer, and then hit the Online button again to bring it online. This should take care of the problem for you. If you have any other questions about this issue or other concerns about your Laserjet 4 series printer, feel free to drop me an email. You can find me at Best Deal Computers as I am the owner. :-)

This is a typical error code. Take a flashlight and look closely inside after removing the cartridge. There probably is a speck of paper that may be covering the sensor. Paper pieces are hard to find sometimes but be patient and look closely lifting up the registration cover assembly. Also look in the tray for a paper that may have not gone through correctly. Remove the tray and also look up in the cavity of the printer.

This sounds to me like the paper inside the tray is a different size than the printer properties is configured to expect as default. To see whether this is the case, right-click on your printer and go to Properties (Printer Properties if you are using Windows 7), then select Preferences... On the next window that appears, click on the Paper tab and look at the Original Size that is selected. Presuming that you have Letter paper in the tray, select the Original Size as Letter and click OK.

That's a "beam detect" error. You probably have to get the laser/scanner replaced. Part Number C2037-69008.

It sounds to me like you may be using this printer through the JetDirect interface and have the printer assigned a different IP address than what the computer is expecting. For example, if the computer is configured to find the printer at 192.168.1.205 and the printer has an address of 192.168.1.120, you will see the "printer offline" message on the computer but the printer is happily "online" according to its point of reference. Another possibility is that the computer has the printer configured to "offline" mode. To check this, right-click on the printer and see whether there is a check mark next to "Use Printer Offline." If so, click on that option and that will remove the check mark, returning the printer to online status.

You have said that you tried cleaning your printer with wet tissue paper. I hope that you weren't using water, window cleaner (such as Windex) or something similar. Anytime that cleaning must be done, one should use rubbing alcohol (aka isopropyl alcohol). Using anything else can be damaging because it will linger in the printer longer instead of evaporating away quickly and that can lead to liquid damage to components that should never get wet, especially if you turn the printer on soon after the cleaning. At this point, you could have several issues going on. Presuming that one or more parts got wet and thus shorted out when power was applied, you could have a problem with the high-voltage power supply, formatter board, laser unit, fusing assembly, or more. Since you have said that the paper now comes out blank, that indicates to me that there is either no image being drawn on the drum of the toner cartridge and/or there is no charging of the paper occurring when it passes over the charging roller. To explain, a laser printer operates by charging the drum with the laser. Anywhere that the laser "writes" is positively charged and when the drum spins around, it picks up toner from the inside of the cartridge. While this is happening, the paper passes over that little foam roller (which is the charging roller) and accepts a uniforn negative charge covering the entire surface of the paper. In perfect time, the paper reaches the image drum where the intended image is transferred by the basic physics of electrical attraction. The paper continues through the printer to head to the fusing assembly. This is the hot part of the printer that actually melts the toner (which is nothing more than a very fine plastic powder) and bonds it to the paper. Given this method of operation, if the laser unit is not working, then the image cannot be written to the drum and therefore there will be no transfer of toner to the drum and subsequently to the paper. If the laser is working but the charging roller is not being properly charged, then the same result of no image is most likely. If the problem is only the fusing assembly, then you would see whatever you printed but you would find that the image was easily removed by wiping it as it was not heated and bonded to the page. To check whether the laser is working, you can send a test page to the printer and wait for the printer to start pulling the paper through. Once the paper is about halfway through the printing, open the printer and pull out the toner cartridge. There is a little door on the bottom that exposes the drum. See whether there is any toner on it that looks like what you were just trying to print. If so, the laser unit seems to be operational. If not, then you have a problem that will potentially be expensive to fix. Further, if the image is on the drum but nothing is getting transferred to the paper, that would indicate that something is amiss with the charging roller. This foam roller is very easily compromised by oils from one's skin (let alone any sort of cleaning solution, even rubbing alcohol), so if you tried cleaning this, you probably made your problems worse by making it so that the roller would not hold a charge any longer. Given the age of the Laserjet 4 series of printers, it is becoming harder to find parts, so while you can spend the money to get it repaired if you wish, I would suggest replacing it with a more modern printer. After all, there are other printers that are faster, more simply designed (meaning fewer parts to fail), and that have cartridges that last just as long (if not longer). As an example, when I finally upgraded from my Laserjet 4M Plus a few years ago, I replaced it with a Samsung ML-3312ND. That printer is just black and white like the Laserjet 4 series, has both USB and Ethernet ports for versatile functionality, and has built-in duplex capability (this allows printing on both sides of the page). The 3312 models have the option of using a cartridge that can print 5000 pages while their cousins, the ML-3712 models, can also use an even larger cartridge that can print 10,000 pages. I hope all this helps!

As one person suggested above, it is possible to share the printer between two machines. All you need to do is set it up as a TCP/IP printer and assign it an address (either through the DHCP server or by giving it a static IP address), then go into the two machines and add the printer as a network printer. When asked about the type of port to use, select Local TCP/IP port... and enter the IP address of the printer. I recommend setting a reserved DHCP address through your router to insure that the printer keeps a constant address and to insure that the router does not accidentally try assigning the same address to something else and therefore cause an IP address conflict.

Repetitive flaws in the printout can indicate problems with the fusing assembly, charging roller, image drum, paper feed rollers, or other parts. The key is to measure how far apart each print defect is as measured from the top of the page to the bottom. For example, if the distance between the first defect and the next is 3.75 inches, the problem is the image drum. You can find a list of the measurements at: HP Support document HP Support Center

Mechanical clutch fault, availability of this spare & replacing is very difficulty.., This mechanism is very delicate & complecated.. Better go for new printer..

This means that the printer is expecting A4 paper rather than letter size or whatever you are trying to use. Check your "Printer Options" on your computer and make sure that the appropriate paper size is selected. A4 is an international standard paper size that is 210 mm (8.27 inches) x 297 mm (11.7 inches) and therefore is just a bit narrower and longer than the American "letter" paper size. To correct this, cancel the print job currently in the printer's memory, change the computer to the proper paper size, and send the print job again.

that is fuser assay problem you need to contact hp service center

There is no downloadable driver for the HP Laserjet 4 series of printers as they are built into Windows starting with Windows XP. The driver that you should select can be either the Laserjet 4 or 4 Plus as they are both the same printer. (What made the 4 into a 4 Plus was the addition of the Jet Direct card that allowed attachment to an Ethernet network.)

This can be caused by the toner cartridge being completely empty or the shipping strip not having been removed prior to installation into the printer. Hope that it is one of these problems because if not, then it could be something much more serious/expensive to fix. For example, it could be the laser itself has failed, so the laser unit would need to be replaced. It might also be the charging roller has failed (but usually this would cause a printout with defects rather than a completely blank page). You might also have a problem with the High Voltage Power Supply.
