HP Color LaserJet Enterprise 700 MFP M775z+ review

Choose the z+ for bulk Letter work and office finishing

The HP Color LaserJet Enterprise 700 MFP M775z+ combines color printing, copying, scanning and analog fax in a substantial floor configuration. Its distinguishing package is the high-capacity paper base and in-line stapler/stacker. It is most useful when an office wants large Letter or A4 supplies ready alongside occasional oversized jobs.

The deciding tradeoff is that its largest paper reservoir does not accept those oversized sheets. The exact CF304A configuration and original paper tables matter more than a family-wide capacity headline. This assessment treats the documented earlier generation as a reference, without claiming a current offer or hands-on performance testing.

3850 sheets is a size-dependent total

The actual z+ column includes a 100-sheet multipurpose tray, a 250-sheet Tray 2 and a 3500-sheet high-capacity input unit. At the stated 75 gsm ordinary-paper basis, that is 3850 included positions. The z model's three 500-sheet trays are a different configuration.

The bulk unit supports only Letter and A4. Legal, A3 and Tabloid use the two smaller standard sources, leaving 350 included positions for those sizes. Someone selecting 3000 sheets of Tabloid would therefore be poorly served despite the large total. The website's matching records that distinction explicitly.

The guide's actual size table confirms automatic print duplex for Letter, Legal, A4, A3 and Tabloid. Media weight and type still matter. Envelopes follow their own one-sided Tray 1 routine, with a ten-envelope limit; the bulk base is not an envelope source.

The feeder reverses originals for their second sides

The included 100-sheet automatic document feeder supports color acquisition and automatic two-sided scanning. HP's exact U.S. specification identifies a reversing ADF. It feeds the second face through the scanning mechanism rather than acquiring both faces simultaneously in one pass.

The U.S. feeder maximum is explicitly 11 × 17 inches. That covers Letter, Legal and Tabloid originals in the documented acquisition route. This assessment keeps the feeder's size evidence separate from the glass. A confirmed flatbed exists, but the read sources do not establish its exact size range sufficiently to promise every large original on that route.

If rapid unattended capture of both faces is central to the office, compare an expressly documented single-pass feeder. Automatic duplex printing and automatic reversing scans remain useful features, but neither substitutes for that mechanism.

Configure the actual computer destination

The operating guide describes Save to Network Folder in detail: place the original on the glass or feeder, select a configured Quick Set or supply a folder path, provide required credentials and start the acquisition. The administrator can prepare destinations through the Embedded Web Server.

This gives a genuine Ethernet arrangement combining printing and computer-folder delivery. The original compatibility list and file-sharing requirements are historical; verify the destination's present permissions and protocol compatibility. A front USB flash-drive scan is another destination, not proof of a USB desktop scanner driver.

Analog fax is included on z+ but requires its own telephone setup. Ethernet provides networking; it does not replace the analog fax line. Ordinary Wi-Fi is optional rather than included simply because mobile printing appears in the catalogue.

PIN jobs are a separate driver workflow

The guide describes creating a Personal Job with the compatible desktop driver and entering a PIN when retrieving it at the touchscreen. Included secure storage supports that documented workflow. Native AirPrint printing does not automatically expose the same driver job-storage controls.

Storage capacity also deserves an actual-unit check: the 2015 operating guide names a 320 GB disk, while newer model specifications list a minimum 500 GB. The existence of secure storage is established; those revision-dependent capacities should not be combined into one invented configuration.

Plan workload, supplies and installation together

HP declares up to 30 Letter pages per minute in color or black. It recommends 2500–7500 monthly printed pages, distinct from the 120000-page maximum duty figure. The actual guide identifies separate 651A black, cyan, yellow and magenta supplies.

Allow delivery and service space for the paper base and finisher, inspect the electrical label and verify current drivers and supply support. Large input capacity reduces refilling for the right paper sizes; it does not make installation, maintenance or every document route automatic.
