This delays the release of the solenoid, which causes the paper to start feeding slightly late. From Wikipedia, the free encyclopedia. An alternative is to enlarge the roller slightly by using heat shrink over the output rollers. There are a couple of solenoids at the paper tray input mechanism that have felt pads designed to cushion them when they snap on, and the glue holding these pads in place can migrate to the surface. This is not a feature of the original Laserjet 4.

Hewlett Packard dominated the laser printing sector during this time laserjet 4v part due to their reliability, relatively affordable pricing, and the spread of LaserJet laserjet 4v models from personal use up to heavy laeerjet use.
Unusually thick laserjet 4v could be run through the printers without jamming by setting the output tray to “Lower face up ” and having it come out the back of the printer. This problem is fixed by removing the felt pads, cleaning off the adhesive isopropyl alcohol works welland placing some electrical 4vv or other material to provide a cushion for the solenoid. The LaserJet 4 series had small printers in the range: The engine over all is reliable.
Another alternative is to use coarse quality abrasive paper such as those used by belt sanders to roughen the surfaces of the rollers. An alternative is laserjet 4v enlarge the roller slightly by using heat shrink over the output rollers. HP LaserJet printers Computer-related lsserjet in This is not a feature laserjet 4v the original Laserjet 4. Replacement kits for these rollers are easily obtainable and can solve the problem.
However laserjet 4v driver for the Lsserjet LaserJet 4 exists in most, even older, software products and is a popular substitute driver for other PCL compatible printers. North America, Europe and Asia.

The error laserjet 4v with each page printed, and eventually the paper is entering the mechanism so late that the printer believes that a jam has occurred.
A quality abrasive is needed laserjet 4v ensure no particles are shed into the mechanism. Unfortunately, accessing the solenoids requires disassembling most of the input mechanism.

Views Read Edit View history. Similar models of earlier HP laser printers had this feature, but it became less common with the later models. There are a couple of solenoids at the paper tray input mechanism that have felt pads designed to cushion them when they snap on, and the laserjet 4v holding these pads in place can migrate to the surface.
This delays the release of the solenoid, which causes the paper to start feeding slightly late. In many cases, the delivery rollers upper and lower in the upper or final stage of the paper exit are worn or unserviceable. Laserjet 4v feature of the 4Si particularly dear to graphic designers was the straight paper feed. It prints laserket pages per minute, and the user cannot extend the laserjet 4v.
