Chapter 1 Product Information

Technology Update

Modular Ink Delivery System

A modular ink delivery system is the separation of ink cartridges and printheads into individual, single-color components. Traditional inkjet printers use one black and one tricolor ink cartridge, each with integrated printheads. HP's modular ink delivery system features four separate ink cartridges--one for each primary printing color--and four corresponding long-life printheads, with tubes connecting the components. Including the standard and high-capacity black ink cartridges, there are actually nine consumables, with only eight used in the printer at one time.

Technology Update

How It Works

By separating the ink cartridge from the printheads, a modular ink delivery system allows the ink supply to remain in a permanent, fixed position. The printheads remain attached to the carriage and move back and forth, delivering ink to the page as the paper advances through the printer. Each printhead and ink cartridge is embedded with a tiny memory device called a smart chip that recognizes and stores the unique operating characteristics of the component to create a totally integrated printing system that ensures consistent, high-quality printing at the lowest cost available.

A unique pressurization system maintains a constant supply of ink to the printheads. Smart chips monitor the amount of ink used by counting every drop that passes through each printhead. When the smart chips sense more ink is needed to maintain continuous printing, a plunger in each cartridge temporarily pressurizes the cartridges to deliver more ink to the printheads. With the modular ink delivery system, ink supply is instantly replenished, even at top speeds.

The new, individually replaceable printheads are designed for long life and each should print 12,000 pages in black, 24,000 pages in color. As a result, you'll go through many ink cartridges before the corresponding printhead will need replacement. With their modular design, ink cartridges contain twice the ink supply of current HP cartridges, so you'll also get longer lasting cartridges. When a component approaches the end of its print life, the smart chip notifies the user through on-screen messages so a replacement can be purchased prior to the part expiring.

By separating the printheads and ink cartridges, you only replace the component that is no longer usable. Printheads can be replaced one at a time without the need for costly or extensive servicing and aren't discarded when the ink is expended. HP printheads also use a wet wiping system to eliminate nozzle clogging that plagues other permanent printhead designs. Component replacement is easy. Simply pull out the used part and snap in a replacement.

The Benefits

Cuts up to 30 percent off the printing costs of other methods

§ Modular design means only the component that is no longer useful is replaced.

§ Longer-life printheads and higher-capacity ink cartridges means less frequent

replacement.

Achieves color laser speed in a personal desktop printer

§ Printheads have 304 nozzles apiece (1,216 total, the most in the industry)

resulting in faster print speeds.

§ Prints in 1/2-inch swath as opposed to the 1/5- or 1/3-inch swaths of integrated

print cartridges.

§ Ink cartridge pressurization system keeps constant flow of ink to printhead. Smart

chips store component information and alert user to low-ink, ink-out and printhead failure status.

The Centronics Parallel Cable has only 8 data lines, 5 status lines, 4 ground lines and ground connections between the host PC and the peripheral. Each of the signal lines has a corresponding bit position in a memory address (register) in the host where data is read or written. Sending data to the printer follows the sequence below:

§ Host places data in Data Out register

§ Host sends pulse on Strobe line

§ Printer sends pulse on Busy in response to pulse on Strobe

§ Printer reads data on Data Out lines

§ Printer sends pulse on ACK (Acknowledge) line after data is read

This method of data transfer is also known as the Compatibility mode and the transfer rate of data is slow. The printer while operating in compatibility mode is capable of indicating limited printer error feedback to the host computer. Such feedback includes:

§ Paper jam

§ Out of paper

§ Printer on or off line

§ Time out

32 nPeriphRequest During ECP mode the peripheral may drive this pin low to request

communications with the host. This request merely “hints” to the host; the host has ultimate control over the transfer direction. This signal provides a mechanism for peer-to-peer communication. This signal is valid in the forward and reverse directions.

36 1284 Active Driven high by host while in ECP mode. Set low by the host to terminate ECP

mode and return the link to the Centronics (uni-directional) mode

The 1284 compliant cable supports the ECP (Extended Capabilities Port) mode in the transfer of data. The ECP protocol includes a series of protocols that differ from standard Centronics parallel port operation. These additional signaling methods allow the host and peripheral to negotiate any of faster transfer modes (e.g. DMA, FIFO and RLE decompression). The protocol is hardware driven and the performance is limited by the ISA bus bandwidth. The primary advantage is that once data transfer is negotiated, data can flow without the need of an acknowledge or a return status signal. This can result in a transfer rate of up to 10 times faster than that of the compatibility mode that the Centronics parallel cable supports.

To transfer data, the host first goes through a negotiation phase, which allows the host and peripheral to select a mutually-supported communications mode. During the negotiation phase, the host indicates which communication mode and options it would like to use via the Extensibility Request Value. If the peripheral device does not support the requested mode or options, it sets the Extensibility Flag low and the interface returns to Compatibility Mode.
