A TMR sensor that includes a free layer having at least one B-containing (BC) layer made of CoFeB, CoFeBM, CoB, CoBM, or CoBLM, and a plurality of non-B containing (NBC) layers made of CoFe, CoFeM, or CoFeLM is disclosed where L and M are one of Ni, Ta, Ti, W, Zr, Hf, Tb, or Nb. One embodiment is represented by (NBC/BC).sub.n where n2. A second embodiment is represented by (NBC/BC).sub.n/NBC where n1. In every embodiment, a NBC layer contacts the tunnel barrier and NBC layers each with a thickness from 2 to 8 Angstroms are formed in alternating fashion with one or more BC layers each 10 to 80 Angstroms thick. Total free layer thickness is <100 Angstroms. The free layer configuration described herein enables a significant noise reduction (SNR enhancement) while realizing a high TMR ratio, low magnetostriction, low RA, and low Hc values.

A managed print service (MPS) system is used to analyze the costs associated with creating hardcopies on document output devices in end user customer environments, develop proposals to optimize the placement and use of document output devices based on the end user customer's desired workflow, and manage the resulting optimized document output device fleet in the replenishment of supplies. MPS providers can also use the system to manage break/fix services to maintain the uptime, or availability, of the fleet of document output devices. The system provides a predictive supplies replenishment module that accounts for variations in user behaviors when determining whether a replacement supply is needed and identifies replacement supplies according to multiple trigger thresholds that are based on calculations of the remaining days of the supplies in the devices. The system also provides device-specific routing labels for different supply parts that are sent to the same shipping address.
