HP ENVY 7640 and HP ENVY 7645 – Review

The difference between the HP ENVY 7640 and HP ENVY 7645 are primarily found is in their availability. Let’s look at their similarities and whether these printers are worth your money.

Since both printers are identical in all aspects, I am going to lay down all of the greatest features these printers have. 

3.5” Colored Touchscreen

The HP ENVY 7640 and 7645 have a colored touchscreen on the front. It is spanning 3.5 inches which is a relatively large screen for a printer. All of the functions these printers have (such as print, copy, scan, and fax) are within the touch of your fingertips. You can also configure each function to your liking. If you want to do a duplex copy or scan, you can do so by setting it with the colored touchscreen. Moreover, once the copy or scan has already been done, you can reduce or enlarge its size from 25% to up to 400%. 

Paper Capacity

The paper capacity a printer can hold is dependent on how large the printers are. Fortunately, both the ENVY 7640 and 7645 are considered the best of both worlds since they are not too bulky yet can still hold a large quantity of paper. Both HP ENVY printers can hold up to 125 sheets of paper in the input tray and 25 sheets in the output tray while standing at only 454 x 503 x 193 mm. 

Wired and Wireless Connectivity

Both HP ENVY printers have wired and wireless connectivity. These printers have an ethernet port that you can use to send and receive a fax. Since both HP ENVY 7640 and 7645 printers have wireless connectivity, you can print documents and photos directly from your smartphones or tablet using wireless printing apps such as Apple AirPrint. Lastly, one of the key features both printers have that I can see be very useful for most people is their Direct Printing using a memory card. 

Printing Capabilities

It is already given that a printer can ‘print’. However, printers differ in their print speed, quality, and features. The HP ENVY 7640 and 7645 have a pretty fast printing speed of 22 papers per minute for monochrome prints and 21 papers per minute for colored prints. Quality is never a problem for both printers since it can print with resolutions of up to 1200 x 1200 rendered DPI for monochrome prints and up to 4800 x 1200 optimized DPI for colored prints. 

Scanning and Copying Capabilities

Copying using both HP ENVY printers is nearly as fast as its printing speed, reaching up to 21 copies per minute for monochrome copies and 19 copies per minute for colored copies. Moreover, you can copy documents to up to 50 copies. In terms of their scanning capabilities, scans are detailed due to its high resolution of 1200 x 1200 DPI. Both HP ENVY 7640 and 7645 printers can scan papers up to the legal size (216 x 297 mm). Scanning via the automatic document feeder is also possible.

Faxing Capabilities 

The HP ENVY 7640 and 7645 are capable fax machines. The fax transmission speed of both printers is faster compared to other fax machines. Both ENVY printers can reach up to 33.6 kbps in transmission speeds. Fax quality is also relatively detailed due to its resolution of 300 x 311 DPI. If you want to keep the fax you receive, you can keep up to 100 pages in black and white. Junk fax is also filtered since both printers require a Caller ID.
