HP Laserjet 4200

About the HP LaserJet 4200 / 4300 Series

A series of fast A4 mono laser printers normally aimed at "workgroup" use (shared in an office). The LJ4200 runs at up to 33 pages per minute and the LJ4300 at up to 43 pages per minute. Output quality is high with a resolution of 1200 dpi at full engine speed.

The built in processor and memory on these models offloads tasks from user computers quickly. Most models are easily shared via a network using HP JetDirect. Optional additions to the basic printer include a range of trays, a duplex unit, envelope feeder and even a stacker / stapler; an accessory not usually available in this price range.

  • 4200 - Q2425A - 4300 - Q2431A - Base model
  • 4200n - Q2426A - 4300n - Q2432A - network
  • 4200tn - Q2427A - 4300tn - Q2433A - network, 2 trays

  • 4200dtnsl - Q2447A - 4300dtnsl Q2448A - network, 2 trays, duplex and stacker / stapler.

The basic difference between the 4200 and 4300 is the processor which is a 300MHz device in the slower printer, matched by 48MB of memory. A 350MHz processor and 64MB memory gives the extra page-formatting capability needed for the LJ4300's speed.

The 4300 also takes a bigger 18,000 page cartridge and has a higher monthly throughput rating reflecting the higher levels of use expected. The LJ 4300 ability to handle higher workloads make it better suited to production tasks like printing catalogues and newsletters.

As might be expected the fusers are different, a more robust unit is used in the 4300. As it happens the 4200 fuser had teething problems with a too-aggressive bend of the foil causing it to delaminate. This problem was cured some time ago. HP changed the design and it has subsequently been reliable. Otherwise the parts are much the same; the difference is in the programming of the formatter board.

Another known defect is that the swing plate assembly which drives the fuser wears and makes grinding noises. The part is readily available but rather a nuisance to replace. There are some instructions

here.

The LJ4200's predecessor was the LJ 4100 which was significantly slower at 24 ppm. Many users found this sort of speed adequate however, hence perhaps the split into the 4200 "budget" and 4300 "premium" range. Other refinements include things like a gear-driven paper tray lifter instead of springs increasing feed reliability and the ability to add two optional trays.

The LJ4200 and 4300 were introduced in the US in November 2002. The range was later extended with the LJ 4250, 4240N and 4350, each being a bit faster and adding features like an embedded JetDirect network connection.

Recent successors are the LaserJet

P4014/ P4515.

Another successor is the

LJ4 345MFP digital copier.

The following information is specific to the HP LJ 4200

Control:

An intuitive layout includes a 4x 20 character LCD panel which gives clear user prompts. Embedded web server and HP Web Jetadmin software on network models.

Duty Cycle:

Maximum monthly print 150,000 pages.

Maximum print speed for the LJ4200 is 33 pages per minute. First page out in less than 8.5 seconds.

Copy Abilities:

The LJ4200 is not a copier however one of the successor products the LJ 4345MFP is a digital copier.

True 1200 dpi with HP Fastres and HP Prores. Ultraprecise toner gives sharp images and moderate photographic ability.

Paper Handling:

A4/letter paper path.

Tray 1:Multifunction tray for 3x5 to 8.5x14 inch paper (76x127 to 216x355 mm). Capacity up to 100 sheets. Weights 60 to 200gsm. Heavy media may need to use the straight- through path to the face-up tray.

Tray 2:Tray 2 built in for standard and some custom paper sizes, A4, A5, letter etc. Up to 500 sheets of 60 to 120 gsm weight.

Tray 3:Tray 3 either a 500 sheet option: as for Tray 2 or a 1500 sheet option: A4, letter and legal paper with weights of 60 to 120 gsm. There can also be a Tray 4 as for Tray 3 but only one 1500 sheet tray can be used - so there would be Tray 1: multifunction, Tray 2: built in 500 sheet, Tray 3: 500 sheet and Tray 4: 1500 sheet giving a total capacity of 2600 sheets.

Face Down:

Paper output is normally to a 250 sheet face down tray on top of the printer. A 500 sheet stacker unit or a 500 sheet stacker with a stapler can be added on top of the printer taking the output capacity to 750 + 50 sheets so it can run largely unattended.

Face Up:

There is a 50 sheet face-up tray at the rear for thicker media.

Duplex:

Duplex and envelope feeder units are also optional.

Processor:

The 4200 has a 300MHz RISC processor

Fuser:

Q2430A Maintenance Kit for LJ4200 220Volt. Yield around 200,000 pages - Q2430-67905

The LJ4200 has a long fuser and roller life and both are likely to be exhausted around the same time - ie the rollers will show wear and cracking at about the same time the fuser foil is doing so. The maintenance kit is therefore a popular repair option.

Fusers are available separately:

RM1-0014 New HP Laserjet 4200 (200/240v) Fuser Unit Yield also 200,000 pages - RM1-0014-230CN

Refurbished fuser and maintenance kits are also available at some cost saving over the new HP item. However note that refurbished fusers and kits are not always available and can raise more issues than a new replacement so they are recommended for experienced engineers changing parts on a familiar printer. Don't buy a refurbished unit if you have one printer that simply must be repaired immediately.

HP's Service Manual cautions that this reset procedure should not be used to clear the message temporarily. If you do clear the message then remember what long-lived items have not been changed yet

HP's Service Manual gives anticipated lives for long-lasting parts:

  • Fuser life for the 4200 and 4300 is 200,000 pages. The transfer roller is expected to have the same life.
  • The tray 1 Pickup roller has an expected life of 100,000 pages. The tray 1 separation pad life is given as 200,000 pages.
  • The Tray 2 Pickup roller has a life of 225,000 pages. The Feed roller has a life of 225,000 pages.
  • The pickup solenoids are given a life of just 200,000 pages in the service manual. In practice the solenoids often outlive the rollers several times.
  • The Cooling fans are all rated for 40,000 hour, about 5 years of constant on service. Ten years or more of working 9 to 5 office hours.

Options:

These printers shipped with a range of optional paper handling accessories. The accessories are no longer likely to be avialable new but may be obtainable in the refurbished market.
