SELECTIVE PRINTING MECHANISMS, i.e. MECHANISMS PRINTING OTHERWISE THAN FROM A FORME; CORRECTION OF TYPOGRAPHICAL ERRORS ## Abstract A nozzle shield assembly includes a band of material having a tag end, a standing end, a first side, and a second side; wherein the second side is at least partially folded against itself, and the standing end is configured to cover a nozzle of a print cartridge. ## Claims ### Claim 1 A method of protecting a cartridge assembly comprising a print head with an array of electronically controlled nozzles for selectively depositing ink, said method comprising: covering said array of electronically controlled nozzles of said print head of said cartridge assembly with a standing end of a ribbon of nozzle tape; folding a tag end of said nozzle tape over said standing end of said ribbon and said array of electronically controlled nozzles for selectively depositing ink; and coupling an indicator to said tag end of said nozzle tape, in which said indicator is positioned to cover a switch on said cartridge assembly, said switch being operable for engaging said cartridge assembly when installed in a printing device. ### Claim 2 (depends on 1) The method of claim 1, further comprising coupling a cap shield to said tag end of said nozzle tape. ### Claim 3 (depends on 1) The method of claim 1, wherein coupling said indicator to said nozzle tape includes coupling a standing end of said indicator to said tag end of said nozzle tape. ### Claim 4 (depends on 1) The method of claim 1, further comprising wrapping said indicator completely around a perimeter of said cartridge assembly and a consumables container housing. ### Claim 5 (depends on 1) The method of claim 1, further comprising wrapping a length of said indicator around an entire perimeter of said cartridge assembly. ### Claim 6 (depends on 1) The method of claim 1, wherein at least said standing end of said nozzle tape covering said nozzles is transparent. ### Claim 7 (depends on 1) The method of claim 1, further comprising: applying an adhesive to a first side of said nozzle tape; and using said adhesive to attach said standing end over said nozzles; wherein a second side of said nozzle tape without said adhesive contacts itself due to said folding. ### Claim 8 (depends on 7) The method of claim 7, further comprising attaching a cap shield to said first side of said nozzle tape such that, following said folding, said cap shield is disposed over said nozzles with said standing end and said folded tag end of said nozzle tape being disposed between said cap shield and said nozzles. ### Claim 9 (depends on 1) The method of claim 1, further comprising disposing said indicator such that said indicator will interfere with a member of a printing device if said indicator is still in place when said cartridge assembly is installed in said printing device. ### Claim 10 A method of protecting a cartridge assembly with nozzle tape and indicating that nozzle tape is attached to said cartridge assembly when said cartridge assembly is coupled to a consumables container, wherein said cartridge assembly comprises a print head with an array of electronically controlled nozzles for selectively depositing ink, wherein an end of said nozzle tape is applied covering and protecting said array of nozzles, and wherein said cartridge assembly is coupled to a consumables container; said method comprising: coupling an indicator to said nozzle tape; and wrapping said indicator completely around said cartridge assembly and said consumables container. ### Claim 11 (depends on 10) The method of claim 10, and further comprising providing instructions on said indicator for removal of said indicator and said nozzle tape. ### Claim 12 (depends on 10) The method of claim 10, further comprising: covering nozzles of said cartridge assembly with a standing end of said nozzle tape; and folding a tag end of said nozzle tape over said standing end of said nozzle tape and said nozzles. ### Claim 13 (depends on 12) The method of claim 12, further comprising coupling said indicator to said tag end of said nozzle tape. ### Claim 14 (depends on 12) The method of claim 12, further comprising coupling a cap shield to said tag end of said nozzle tape. ### Claim 15 (depends on 14) The method of claim 14, further comprising positioning said cap shield such that said cap shield is disposed over said nozzles, with said standing end and said folded tag end of said nozzle tape being disposed between said cap shield and said nozzles. ### Claim 16 (depends on 12) The method of claim 12, wherein at least said standing end of said nozzle tape covering said nozzles is transparent. ### Claim 17 (depends on 12) The method of claim 12, further comprising: applying an adhesive to a first side of said nozzle tape; and using said adhesive to attach said standing end over said nozzles; wherein a second side of said nozzle tape without said adhesive contacts itself due to said folding. ### Claim 18 (depends on 17) The method of claim 17, further comprising attaching a cap shield to said first side of said nozzle tape using said adhesive such that, following said folding, said cap shield is disposed over said nozzles, with said standing end and said folded tag end of said nozzle tape being disposed between said cap shield and said nozzles. ### Claim 19 (depends on 10) The method of claim 10, further comprising disposing said indicator such that said indicator will interfere with a member of a printing device if said indicator is still in place when said cartridge assembly is installed in said printing device. ### Claim 20 (depends on 10) The method of claim 10, wherein said indicator is positioned to cover a switch on said cartridge assembly, said switch being operable for engaging said cartridge assembly when installed in a printing device. ### Claim 21 A method of protecting a cartridge assembly comprising: covering nozzles of said cartridge assembly with a standing end of a ribbon of nozzle tape; disposing a cap shield on said nozzle tape; folding a tag end of said nozzle tape over said standing end of said ribbon and said nozzles; and positioning said cap shield such that, following said folding, said cap shield is disposed over said nozzles, with said standing end and said folded tag end of said nozzle tape between said cap shield and said nozzles.
