An end portion of the first tubing is arranged in an active position to provide the first printing fluid to a printhead in the printhead slot. An end portion of the second tubing is arranged in a standby position to not provide the second printing fluid to a printhead. A mechanical structure to which the end portion of the first tubing is attached allows to remove the end portion of the first tubing from the active position and to arrange the end portion of the second tubing in the active position. ## Claims ### Claim 1 A printing apparatus, comprising: a support member having a printhead slot; a first tubing to provide a first printing fluid; and a second tubing to provide a second printing fluid; wherein a printhead-side end portion of the first tubing is arranged in an active position to provide the first printing fluid to a printhead in the printhead slot; wherein a printhead-side end portion of the second tubing is arranged in a standby position to not provide the second printing fluid to a printhead; wherein a mechanical structure to which the printhead-side end portion of the first tubing is attached allows to remove the printhead-side end portion of the first tubing from the active position and to arrange the printhead-side end portion of the second tubing in the active position. ### Claim 2 (depends on 1) The printing apparatus of claim 1, the apparatus further comprising: a first printing fluid cartridge slot; and a second printing fluid cartridge slot; wherein the first tubing is arranged to receive the first printing fluid from a first printing fluid cartridge in the first printing fluid cartridge slot; and wherein the second tubing is arranged to receive the second printing fluid from a second printing fluid cartridge in the second printing fluid cartridge slot. ### Claim 3 (depends on 1) The printing apparatus of claim 1, wherein the printhead-side end portion of the first tubing comprises two tube endings and wherein the printhead-side end portion of the second tubing comprises two tube endings. ### Claim 4 (depends on 3) The printing apparatus of claim 3, the apparatus further comprising a recirculation unit, wherein the printhead-side end portion of the second tubing is connected to the recirculation unit, when in the standby position. ### Claim 5 (depends on 1) The printing apparatus of claim 1, the apparatus further comprising an end portion cover, wherein the printhead-side end portion of the second tubing is covered by the end portion cover, when in the standby position. ### Claim 6 (depends on 1) The printing apparatus of claim 1, wherein the mechanical structure comprises a skid to which the printhead-side end portion of the first tubing and the printhead-side end portion of the second tubing are attached and wherein the support member comprises a guide pillar for guiding a displacement of the skid relative to the support member. ### Claim 7 (depends on 1) The printing apparatus of claim 1, wherein the mechanical structure comprises a pivot member which is pivotally coupled to the support member and to which the printhead-side end portion of the first tubing and the printhead-side end portion of the second tubing are attached. ### Claim 8 (depends on 1) The printing apparatus of claim 1, wherein the mechanical structure comprises a base portion and a locking portion, wherein the locking portion locks the printhead-side end portion of the first tubing to the base portion when in a first position, and unlocks the printhead-side end portion of the first tubing from the base portion when in a second position. ### Claim 9 (depends on 1) The printing apparatus of claim 1, wherein the printing apparatus is an inkjet printing apparatus comprising the printhead and wherein the first printing fluid is a first ink and wherein the second printing fluid is a second ink. ### Claim 10 (depends on 9) The printing apparatus of claim 9, wherein the first ink and the second ink are different inks. ### Claim 11 (depends on 10) The printing apparatus of claim 10, wherein the first ink and the second ink are inks of different colors. ### Claim 12 (depends on 1) The printing apparatus of claim 1, wherein the printhead-side end portion of the first tubing has a different shape than the printhead-side end portion of the second tubing. ### Claim 13 (depends on 12) The printing apparatus of claim 12, further comprising a printing fluid cartridge in the printhead slot and wherein the different shape of the printhead-side end portion obviates connecting the second tubing with the printing fluid cartridge. ### Claim 14 A support member for a printing device, the support member comprising a printhead slot; wherein a portion of a first tubing and a portion of a second tubing are attached to the support member; wherein a printhead-side end portion of the first tubing is arranged in an active position to provide a printing fluid to a printhead in the printhead slot; wherein a printhead-side end portion of the second tubing is arranged in a standby position to not provide a printing fluid to a printhead; wherein the support member allows switching of the printhead-side end portion of the second tubing to the active position while the portion of the first tubing and the portion of the second tubing are attached to the support member. ### Claim 15 A method of replacing an inkjet printhead in a printing apparatus, the method comprising: printing on a printing medium with a first ink provided to a first inkjet printhead via a first tubing; removing the first inkjet printhead from a printhead slot; mounting a second inkjet printhead to the printhead slot; connecting a second tubing to the second printhead; and printing on a printing medium with a second ink provided to the second inkjet printhead via the second tubing; wherein a portion of the first tubing and a portion of the second tubing is attached to the printing apparatus during the whole procedure.
