The 7800/9800 Series Printers
Epson has made 3 series of 24″ and 44″ printers. First they produced the 7800/9800 series. These printers used the DX5 8-Color Piezo Head. It is considered to have been improved by Epson’s new advanced MicroPiezo TFP head technology. We’ve gotten great results from the DX5 head. It just keeps working. It handles almost any inkjet ink formula with ease. It recovers from clogs well. It prints great whether your printing pigment, dye, or sublimation inks. This head seems reliable, while also producing brilliant results.
Ink cartridges are pressurized by an air pump and sensor that maintains the proper air pressure. This is another failure point that may cause drop outs. Fortunately, the printer is easy to repair. The center cover is held on by only four screws, allowing for easy removal and access to the carriage for head repairs. Replacing the print head and dampers can be done in as little as half an hour. A repair wizard is also available, giving users complete access to the printer for controls.
Being an 8-color printer, there are also many options for different ink sets from third party companies.
American Inkjet Systems highly recommend these printers.
The 7880/9880 Series Printers
The second generation of the 7800/9800 series uses a head with a special coating to prevent dust buildup. It also introduced a new magenta called “vivid magenta”.
With this generation, Epson locked the user out of the printer for head replacement, as well as counters, probably with the intension of keeping third party inks out of their printers. The head is more sensitive to the structure of ink is less forgiving when it comes to clogging. That said, these printers offer all the same features as the previous models. They hold up well and are as easy to repair as their predecessors. Head replacement is less than $400.
The 7890/9890 Series Printers
The third generation of the 7800/9800 series uses the head found in the 9900 series printers—a high speed head with a special coating and more nozzles, for a price over $1000. We’ve found this head to be more sensitive to the structure of ink and more likely to clog with low-quality inks. With the introduction of this series, they added a host of new electronic features. This also included the vivid magenta, introduced in the 9880 series.
Epson locked the user out of the printer for head replacement, as well as counters, probably with the intension of keeping third party inks out of their printers. All the electronic parts offer new points of failure. The printer only uses 8 nozzle groups, so swapping between matte and gloss black will require a full change over. The cost of the capping station is about twice the cost of the previous models.
However, all the electronic parts offer ease of cleaning. The user can clean groups of heads individually instead of the entire ink set. With 9 slots you can easily more easily go between matte and gloss black. Setting media up does not require a rod, but relies on the media core. It automatically move the paper down and winds it up. The speed of printing is significantly faster than the previous models. The printer holds up well, but it is not as easy or affordable to repair as the base 9800 series.
