smartek™ 4100 Chip Functionality Guide

Chip technology

Functionality Overview

The smartek™ chip delivers the same Supplies Status cartridge usage information and printer functions as the OEM chip. The 4100 chip is not a “lock-out” chip design such as the Xerox® and Lexmark® chips familiar to the industry. Instead, the 4100 is better described as a “limited functionality” chip. The 4100 chip has two core functions:

1.It transmits, receives and stores data.

2.It works like a light switch to “turn on” four key areas of printer functionality.

These printer functions are critical to efficient, cost-effective printer usage. The functional areas are listed below, along with a chart that lists the detailed functions.

•Printer Operations

•Printer Control Panel Information

•Printed Information Menu Supplies Status Information (Fig. 1 & 2 pg. 7)

•Printer Embedded Java Webserver Supplies Status Information (Fig. 3 & 4 pg. 7)

Types of Data Held by Chip

The chip holds both fixed and variable data. The fixed data is written to the chip at the time it is manufactured. The variable data is written to the chip as the cartridge is consumed in the printer. The variable data essentially is the usage history of the cartridge.

Fixed Chip Data:	Variable Chip Data:
HP Cartridge Part Number	Toner % of Life Remaining
Cartridge Manufacture Date	Toner Low Reached
Cartridge Serial Number	Toner Out Reached
	Total Pages Printed
	Page Count by Paper Size
	Number of Jobs Processed
	Marked as Reordered
Chip Design Details

All communication between the chip and the

printer are accomplished using RF (radio frequency) technologies. A micro-scale antenna is housed within the chip casing and the printer also features a corresponding antenna. All data, signals and power supply are transmitted over this wireless connection.
