An inkjet printer comprises a printhead that includes a number of printhead segments that span a print area so that portions of consecutive printhead segments overlap in common print areas. The transmission coil is configured to transmit a transmission signal having a carrier. The heat dissipating device also includes surface perturbations. A flexible anchoring member is configured to be inserted through the side opening and through the curved bore of the spacer member such that a distal end portion of the flexible anchoring member extends out of the second opening at an angle relative to the one of the top wall and the bottom wall of the spacer member. The differential output signals of the n selection units are combined whereby unwanted crosstalk from channels other than a selected channel are removed by cancellation. The polyols, which contain aliphatic or mixed phenolic and aliphatic hydroxyl groups, are the reaction products of aralkylated phenols or phenol aralkylation polymers with an oxyalkylating agent selected from alkylene oxides and alkylene carbonates.
