Strengths: Fine when it works.

Weaknesses: Print heads fail unexpectedly and for no appear ant reason.

Summary: It's no surprise that print heads are the most expensive accessory. I've had to make several replacements and they continue to fail. Designed Obsolescence has crossed my mind more than once.

Strengths: Generally a solid product but....

Weaknesses: We cannot figure out how to scan a multi page document. This scanner makes each page of a multi page doucment a separate jpg....It is ridiculous.

Summary: I would not reccomend this produce. The user guide was very difficult and I cannot find any information on how to deal with this problem.

Strengths: Easy to set up; lots of connection choices; great quality printing; ink lasts a long time (with the retail cartridges).

Weaknesses: Some scanner driver/software complications were resolved with new driver/software install. Manual feeder occasionally would misfeed a document and then it would jam.

Summary: This has been the best multi-purpose printer we have owned. For our small, Macs-only office, it has been the perfect addition for our printing, scanning, copying and faxing needs. We have installed eight of these printers in other offices with no complaints.

Strengths: None. Product prints fast but jams and very glitchy.

Weaknesses: Had issues with this unit in our office. We had over 20 of these and every single one ends up breaking down.

Summary: I Dont recommend this unit to anyone. The product is not well built and will break down. The L7680 is built very poorly and is primarily made from cheap plastic. There are much better machines from Canon than this HP unit. THe L7680 has very well known problems and is the worst unit you could purchase. Stay away from the L7580, L7680, L7780 these are all the same units with different options on them. We had over 20 of these at our office and not a single one lasted over 6 months.

Strengths: Very fast print speeds for text and photos; excellent text output quality; relatively low cost per page; great feature set (duplex printing and ADF, standalone and network fax, scan to network)

Weaknesses: Limited paper handling (no manual feed slot), poor color photo output, buggy software installation and conflicts with other image acquisition software

Summary: Despite the many negative reviews posted here and elsewhere, I bought one of these printers. I should have paid more attention. I spent at least 20 hours, including a 3 hour HP tech support call, trying to get the printer software to install with a network connection on 2 of 3 WinXP and 1 of 2 Vista computers. There is a conflict that neither I nor tech support could identify or workaround. In addition, the installer will not run more than once for the same printer, requiring a complete uninstall and manually removing registry entries between attempts. After 3 hours, the HP tech support person decided there was something wrong with my router, and I had to open ports in order to get the network install to work, even though I told her I had installed it successfully on a third WinXP PC and a brand new Vista PC. She agreed to call me back in an hour, after I had reconfigured my router, but never did so. I had the same install problems with the latest software downloaded from the HP web site (8.0.1) and the CD that came with the printer (8.0.0). I finally installed it with a USB cable, just to test the print quality. Text output was very good and very fast. Photo output quite fast, but poor quality, with visible banding and lines that did not appear when printed on my old slow Canon photo printer. I tried one color copy: the red text on the original printed as orange on the copy. I don't know if the problem is with the scanner or the printer. For an office printer, this unit also has very limited paper handling: a single tray, and no manual feed slot. I'm returning it for a refund. Next time I will pay more attention to the negative reviews. Fortunately, I purchased the printer from a vendor (Amazon) that accepted a return, even though I had installed the ink cartridges and used the printer. In addition, 3 months later, after having run the full "level 4 uninstall" at least twice on all 5 computers that I used in my initial tests, there is still some HP software running that periodically checks for updates on the internet on 2 of my computers.

Strengths: great reviews and advertising

Weaknesses: 100% failure rate so far

Summary: bought this for my library in switzerland, based on reviews and cash back [should have been a warning in itself]first machine dead out of the box, though cost me two hours on phone with moroccan 'support' to determine that while he attempted to fill out various formssecond machine lit up but OK button on control panel dead so could not set upthird machine set up and actually made one copythen reported problems with colour printhead, after reset reported problems with black printheadnow awaiting delivery of FOURTH machine

Strengths: Not Known

Weaknesses: Out of the box, our L7680 has 2 problems. It erroneously says the printhead latch is not closed. It also says the carriage head is jammed, but paper has never been loaded into this machine.

Summary: In addition to the probs above, the machine is making a lot of noise and it does not sound at all like a properly working printer. We were quite careful to remove all packaging materials and install printheads and ink cartridges carefully. It is going back to the store as soon as we finish eating dinner...

Strengths: Speed, cost/yield of ink cartridges, duplexer, Ethernet

Weaknesses: Reliability Unknown

Summary: Before you knock the printer for draining the ink when you first fire it up, take a look at the design. The ink cartridges connect to the print heads through long flexible tubes. First time you fire it up, you're going to waste a bunch of ink filling the lines and printheads, but you shouldn't have to do that ever again (unless you replace the printheads). This also explains the startup noise people have been complaining about - it has to pump a lot to prime the lines and printheads. I will be buying this thing tomorrow, and look forward to a long life in my home office.

Strengths: > Excellent printing...> Fantastic feature list...> Low cost per page

Weaknesses: > Noisy...> Extensive start-up process (plan to leave it always on)...> Cheap plastic parts, not durable enough for actual office use

Summary: For eleven years my trusty HP Officejet Pro 1150C stood ready to make copies and serve as a main color printer for my small home business. Finally, I decided it should be replaced when my third super-deep cleaning revealed seriously worn parts (although it still functioned with only an occasional unexpected 'clunk'). Enter the L7650. It seemed to have all the features I always wanted in the old 1150C.On arrival, the L7650 paper tray cover had a broken catch. The first-time out-of-the-box start-up process takes 12 minutes for this printer--during which time it sounds much like a paper shredder. In normal operation this unit is louder than any of my other three printers. After a couple copies the ADF (document feeder) sensor mechanism failed. Following these issues, and an hour on the phone with HP customer support for some software glitches on install, I concluded the L7650 wasn't ready for prime time. HP offered to send a replacement unit in 5 days, but I told them mine was going back to the store. I'll wait to see if there is a rev. 2 version before trying a second unit. My old 1150C is back on duty, working 'just fine' after 11 years.

Strengths: I replaced HP officejet 9110 (home office use), so I printed documents to compare the printing. I found the documents on the officejet pro L7680 to be significantly better in detail, color & quality.

Weaknesses: You need to reinstall a couple of times and the ink cartridge will drop to 75% ink remaining in all colors.

Summary: After completing set up, my ink gauge dropped to 75% in all colors. When I called HP, I was told that the cartridges w/printer have less volume then the standard size 88 ink cartridge. So, you need to spend $100 for the regular ink cartridge to actually judge the output usage. Therefore, I am planning on returning the printer to the HP store and wait for more reviews on it. I have 21 days to figure if the usage meets HP's claims.
